What is the verbal description for y=3x-2

25 cakes can be completely decorated using 4 gallons of icing.

Step-by-step explanation:

Given:

4 gallons of icing

16 cups =1 gallon

No. of icing cups = [tex]4\times16[/tex] cups

       =64 cups

No. of cups required to decorate and frost a cake= 4% of total no. of icing cups

          = [tex]\frac{(4\times64)}{100}[/tex]

          = 2.56

2.56 cups of icing is required to decorate each cake.

Maximum no. of cakes decorated = [tex]\frac{ (64\times1)}{2.56}[/tex]

                    = 25

25 cakes can be completely decorated using 4 gallons of icing.

Answer:

C

Step-by-step explanation:

The first link is for the first question, and the second one is to the second question I hope this helps!

Answer:

a) Given in attachment.

b) Quadrilateral formed is a rhombus. Because length of all the sides are equal and angle between adjacent sides is not 90°.

c) 24 unit².

Step-by-step explanation:

Let rectangle be ABCD with length 8 and width 6

And mid-points be E,F,G,H

Now, join the mid-points .

we know that angle between adjacent sides in a rectangle is 90°.

⇒ ΔFAE forms a right angle triangle with 90° at A.

By, pythagoras theorem , EF² = AF² + AE²

⇒ EF² = 3² + 4² = 25

⇒ EF = 5;

In the same way, FG = GH = HE = 5

⇒ the quadrilateral is either square or rhombus.

Now, from ΔFAE,   sin(∠AEF) = [tex]\frac{4}{5}[/tex]

(sinФ = opposite side / hypotenuse)

⇒ ∠AEF = 53°;

In similar manner;

∠DEH = 53° . Now ∠FEH = 180 - 53 - 53 = 74° (sum of angles on a straight line is 180°)

⇒ the quadrilateral is rhombus has angle between adjacent sides is 53° and not 90°.

Now, to find the area of rhombus, join EG and FH. And name the intersection point as J.

consider ΔEJF,

it is a right angled triangle at J, and also quadrilateral AFJE forms rectangle, as diagonals intersect perpendicular in a rhombus.

⇒ FJ = 3 and EJ = 4.

⇒ area of this triangle = 1/2 × base × height

                                     = 1/2 × EJ × JF = 1/2 × 3 ×4 = 6

similarly triangles FJG, GJH, HJE.

⇒ area of rhombus = 6+6+6+6 = 24.

Answer:

The solution of the inequality is:

[tex]x>2[/tex]

Step-by-step explanation:

Given inequality:

[tex]-1 >-2(x - 4)-5(4x-7)[/tex]

Solving the inequality.

Using distribution.

⇒ [tex]-1 >(-2x) +((- 4)(-2))+(-5\times4x)+((-5)(-7))[/tex]

⇒ [tex]-1 >-2x +8-20x+35[/tex]

Combining like terms

⇒ [tex]-1 >-2x-20x+35+8[/tex]

⇒ [tex]-1 >-22x +43[/tex]

Adding [tex]22x[/tex] both sides.

⇒ [tex]-1+22x >-22x +43+22x[/tex]

⇒ [tex]-1 +22x> 43[/tex]

Adding 1 both sides.

⇒ [tex]-1+1 +22x> 43+1[/tex]

⇒ [tex]22x>44[/tex]

Dividing both sides by 22.

⇒ [tex]\frac{22x}{22}>\frac{44}{22}[/tex]

⇒ [tex]x>2[/tex]

Thus, the solution of the inequality is:

[tex]x>2[/tex]

Final answer:

To maintain the same weekly revenue after reducing her pot price from $24 to $16, a potter working 4 days a week must increase her daily production from 14 pots to 21 pots, which is an increase of 7 pots per day.

Explanation:

The question involves a potter who initially makes 14 pots per day and works 4 days a week, charging $24 per pot. To find out by how many pots per day she must increase her production after lowering her price to $16 per pot, to make the same amount of money, we first calculate her current weekly revenue:

After reducing the price to $16 per pot, we need to determine how many pots per day she needs to sell to maintain the same weekly revenue of $1,344:

Therefore, she needs to sell 7 more pots per day (21 pots - 14 pots) to maintain her weekly revenue.

Answer:

∠ZPB and ∠APZ are two adjacent supplementary angles

Step-by-step explanation:

we know that

Two angles are Adjacent when they have a common side and a common vertex

Two angles are supplementary if their sum is equal to 180 degrees

In this problem we have that

[tex]m\angle ZPB=90^o[/tex] ----> given problem

[tex]m\angle APZ=90^o[/tex] ----> given problem

so

[tex]m\angle ZPB+m\angle APZ=180^o[/tex]

∠ZPB and ∠APZ are supplementary angles

and

∠ZPB and ∠APZ have a common side (ZP) and a common vertex (P)

therefore

∠ZPB and ∠APZ are two adjacent supplementary angles

Answer: ∠ZPB and ∠APZ are two adjacent supplementary angles

Answer:

y = - 3x + 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (3, - 4) and (x₂, y₂ ) = (1, 2)

m = [tex]\frac{2+4}{1-3}[/tex] = [tex]\frac{6}{-2}[/tex] = - 3, thus

y = - 3x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (1, 2), then

2 = - 3 + c ⇒ c = 2 + 3 = 5

y = - 3x + 5 ← equation of line

Answer:

y=-3x+5

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(2-(-4))/(1-3)

m=(2+4)/-2

m=6/-2

m=-3

y-y1=m(x-x1)

y-(-4)=-3(x-3)

y+4=-3(x-3)

y=-3x+9-4

y=-3x+5

Answer:

3

Step-by-step explanation:

For this question, you need to make change the denominators of the fractions to be equal, making them the same lowest common denominator.

8/9 -> 40/45

4/15 -> 12/45

Since 12 goes into 40 3 1/3 times, he can patrol that many neighborhoods in 8/9's of an hour, which is rounded to 3 because he doesn't have enough time for 4.

To determine if the sheriff can patrol 2, 3, 4, or 6 neighborhoods in 8/9 of an hour, we need to calculate the time it takes to patrol a single neighborhood and then divide the given time by that value. The answer is 10/3, which means the sheriff can patrol 2, 3, 4, or 6 neighborhoods in 8/9 of an hour.

To determine if the sheriff can patrol 2, 3, 4, or 6 neighborhoods in 8/9 of an hour, we need to calculate the time it takes to patrol a single neighborhood and then divide the given time by that value.

Given that it takes 4/15 of an hour to patrol a single neighborhood, we can divide 8/9 by 4/15.

To divide fractions, we multiply by the reciprocal, so 8/9 ÷ 4/15 becomes 8/9 × 15/4. Multiplying across, we get (8 × 15) / (9 × 4) = 120 / 36 = 10 / 3.

Answer: [tex]4\ feet[/tex]

Step-by-step explanation:

The exercise provides you the following Quadratic function:

[tex]h(t)=4+60t-16t^2[/tex]

You know that it represents the height (in feet) of the ball as a function of the time (in seconds) since the ball hit the bat.

Based on this, you can conclude that when the ball strikes the bat the time in seconds is:

[tex]t=0[/tex]

Therefore, in order to calculate the height in feet of the ball when it strikes the bat, you need to subsititute [tex]t=0[/tex] into the function and    then evaluate.

So, you get:

 [tex]h(0)=4+60(0)-16(0)^2\\\\h(0)=4[/tex]

First, do distributive property:

2(5+3x)+(x+10)  Distribute the 2 to the 5 and the 3x; multiply them

10+6x+x+10      Since (x+10) would be 1 times x and 10, it's just x+10

Then, do communitive property:

10+6x+x+10     What we found in the last step, now combine the like terms

20+7x              This is what you get since 10+10=20 and 6x+x=7x

The answer:

20+7x or 7x+20

g(x) = 2x – 8

f(x) - g(x)

Step-by-step explanation:

The diagram shows Pascal's triangle. Pascal's triangle is a triangular array of the binomial coefficients.

The entry in the [tex]n^{th}[/tex] row (start counting rows from 0) and [tex]k^{th}[/tex] column (start counting columns from 0) of Pascal's triangle is denoted by

[tex]C^n_k=\left(\begin{array}{c}n\\ k\end{array}\right)[/tex]

Coefficient 20 stands in 6th row, then n = 6 and in 3rd column, so k = 3.

Hence,

[tex]20=C^6_3=\left(\begin{array}{c}6\\ 3\end{array}\right)=\dfrac{6!}{3!(6-3)!}[/tex]

Answer:

x^3 - 3x^2 - 3x + 9 + (-36/(x+3))

OR

x^3 - 3x^2 - 3x + 9 - (36/(x+3))

Step-by-step explanation:

First set the divisor equal to 0:

x + 3 = 0

Subtract 3 from both sides

x = -3

This is what you'll divide the dividend by in synthetic division.

Take the coefficents of each term in the dividend. Do not forget the 0 placeholders:

x^4 + 0x^3 - 12x^2 + 0x -9

Coefficents: 1. 0.  -12. 0 -9.

Please see the image for the next steps.

The remainder is -36. Put the remainder over the divisor and add it to the polynomial (shown in image)

-36/(x+3)

Divide using synthetic division the remainder is -36. Put the remainder over the divisor and add it to the polynomial -36/(x+3).

First set the divisor equal to 0:

x + 3 = 0

Subtract 3 from both sides

x = -3

This is what you'll divide the dividend by in synthetic division.

Take the coefficents of each term in the dividend. Do not forget the 0 placeholders:

[tex]x^4 + 0x^3 - 12x^2 + 0x -9[/tex]

Coefficents: 1. 0.  -12. 0 -9.

The remainder is -36. Put the remainder over the divisor and add it to the polynomial -36/(x+3).

For this case we must simplify the following expressions:

[tex]m ^ 3 + m ^ 3\\10 + 3c + 5d-7c + d[/tex]

Expression 1:

[tex]m ^ 3 + m ^ 3 =[/tex]

They are similar terms so we can add.

[tex]2m ^ 3[/tex]

Expression 2:

[tex]10 + 3c + 5d-7c + d =[/tex]

We add similar terms taking into account that:

Equal signs are added and the same sign is placed.

Different signs are subtracted and the major sign is placed.

[tex]10 + 3c-7c + 5d + d =\\10-4c + 6d[/tex]

Answer:

[tex]m ^ 3 + m ^ 3 = 2m ^ 3\\10 + 3c + 5d-7c + d = 10-4c + 6d[/tex]

Answer: [tex]S_{29}[/tex] = 2001

Step-by-step explanation:

Since the sequence is an arithmetic sequence , it means that a common difference must exist.

Let the terms in the sequence be [tex]T_{1}[/tex] , [tex]T_{2}[/tex] , [tex]T_{3}[/tex] , [tex]T_{4}[/tex] , ...

Then common difference = [tex]T_{2}[/tex] - [tex]T_{1}[/tex] = [tex]T_{3}[/tex] - [tex]T_{2}[/tex] = 8

That is , the common difference (d) = 8

The formula for calculating sum of  n terms is given by :

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a + (n-1)d ]

Where ;

n = number of terms

a = first term

d = common difference

From the question :

n = 29

a = -43

d = 8

Substituting into the formula , we have

[tex]S_{29}[/tex] = [tex]\frac{29}{2}[/tex] [ 2{-43} + (29-1)(8) ]

[tex]S_{29}[/tex] = [tex]\frac{29}{2}[/tex] (-86 +224)

[tex]S_{29}[/tex] = [tex]\frac{29}{2}[/tex] ( 138)

[tex]S_{29}[/tex] = [tex]\frac{4002}{2}[/tex]

[tex]S_{29}[/tex] = 2001

Polar form: (r,θ)

Using these formulas:

x²+y²=r²

tan(θ)=y/x

We have the point (1,1) in cartesian coordinates. We need to find r and θ to get it in polar form.

r²=1²+1²

r²=2

r=±√2

tan(θ)=1/1

tan(θ)=1

θ=π/4 radians or 45 degrees

Polar coordinates: (√2,π/4)

The gardeners should buy 48 white and 116 pink hydrangeas altogether

Step-by-step explanation:

The given is:

We need to find how many white and how many pink hydrangeas the gardeners should buy altogether

Assume that the number of white hydrangeas is x and the number of pink hydrangeas in the first bed

∵ The first bed has x white hydrangeas

∵ The first bed has y pink hydrangeas

∵ The total of white and pink hydrangeas in 1st bed is 45

- Equate the sum of x and y by 45

∴ x + y = 45 ⇒ (1)

∵ In the 2nd bed the number of the white hydrangeas is 2 times

   as in the 1st bed

∵ The number of the pink hydrangeas is 3 times as in the 1st bed

∵ The number of the hydrangeas in the 2nd bed is 119

- Multiply x by 2 and y by 3, then add the products and equate

  the sum by 119

∴ 2x + 3y = 119 ⇒ (2)

Now let us solve the system of equations

Multiply equation (1) by -3 to eliminate y

∵ -3x - 3y = -135 ⇒ (3)

- Add equations (2) and (3)

∴ -x = -16

- Divide both sides by -1

∴ x = 16

- Substitute the value of x in equation (1) to find y

∵ 16 + y = 45

- Subtract 16 from both sides

∴ y = 29

∵ The number of the white hydrangeas in the 1st bed is x

∵ The number of the white hydrangeas in the 2nd bed is 2x

∴ The total number of the white hydrangeas = x + 2x = 3x

∵ x = 16

∴ The total number of the white hydrangeas = 3(16) = 48

∵ The number of the pink hydrangeas in the 1st bed is y

∵ The number of the pink hydrangeas in the 2nd bed is 3y

∴ The total number of the pink hydrangeas = y + 3y = 4y

∵ y = 29

∴ The total number of the pink hydrangeas = 4(29) = 116

The gardeners should buy 48 white and 116 pink hydrangeas altogether
