Answer:

[tex]6x-4y[/tex] →  4.  [tex]2(3x-2y)[/tex]

[tex]6-4x[/tex] →    3.  [tex]2(3-2x)[/tex]

[tex]6x-4x[/tex] →  1. [tex]2x[/tex]

[tex]6x-4[/tex] →   2. [tex]2(3x-2)[/tex]

Step-by-step explanation:

You need to:

 Factor out 2 from [tex]6x-4y[/tex],  then you get the equivalent expression:

[tex]=2(3x-2y)[/tex] this matches with OPTION 4

Factor out 2 from [tex]6-4y[/tex], then you get the equivalent expression:

[tex]=2(3-2x)[/tex] this matches with OPTION 3

Make the subtraction for [tex]6x-4x[/tex],  then you get the equivalent expression:

[tex]=2x[/tex] this matches with OPTION 1

Factor out 2 from [tex]6x-4[/tex],  then you get the equivalent expression:

[tex]=2(3x-2)[/tex] this matches with OPTION 2

Answer:

6x-4y=2(3x-2y),

6-4x=2(3-2x),

6x-4x=2x,

6x-4=2(3x-2)

Step-by-step explanation:

We have been given 4 expressions

6x−4y, 6−4x, 6x−4x, 6x−4

Now we need to simplify or factor so that we can match each expression with an equivalent expression.

6x-4y=2(3x-2y)

6-4x=2(3-2x)

6x-4x=2x

6x-4=2(3x-2)

Now we can easily see that right side is unique for each of the given expression which can be easily matched with given choices.

Step-by-step explanation:

Graphing the best-fit quadratic curve for the data-set can be done using Ms. Excel Application.

The first basic step is to enter the data into any two adjacent columns of the excel workbook. Highlight the two columns where the values have been entered, click on the insert tab and then select the x,y scatter-plot feature. This will create an x,y scatter-plot for the data.

Next, click on the Add Chart Element feature and add a polynomial trend-line of order 2 which is basically a quadratic curve. Finally, check the display equation on chart box. This step will plot the quadratic curve as well as give the equation of the best-fit quadratic curve.

The attachment below shows the best-fit quadratic curve to the data-set and its corresponding equation.

A good approximation for the value of c from the equation is thus 3. This is simply the y-intercept of the curve. 3.21 is closer to 3.

Check the picture below.

recall the diameter is twice as long as the radius, thus d = 2r = 38.42 or rounded up to 38.

Answer: I think the answer is the second box.

Step-by-step explanation: It says 20 males have watched the show. I hope I helped you. If I am wrong, tell me in a polite way. :D

Hello there! The answer is the second chart, or B.

To find the answer, look at the parts of the question.

Let's start in the beginning. Note how it says "Of the 80 participants, 30 were male and 50 were female". This means that, looking at the options, in the "total" row, there should be a value for "30" by male, "50" by female and 80 at the bottom. This means that it cannot be A since this option says that there were 80 females and 80 males and 160 total, or C since it says there are 80 males and 55 females with a total of 135.

Next, it says that 45 have watched the show and 35 have not. If you look at the options left B and D, the only one the has these numbers for have and have not watched is B, making this the correct answer.

I hope this helps and have a great rest of your day! :)

Answer: The graph of g(x) is the graph of f(x) compresed vertically.

Step-by-step explanation:

Given the parent function [tex]f(x)^2[/tex], there are some transformations rules:

If [tex]f(x)=a(x^2)[/tex] when [tex]a>1[/tex], then it is stretched vertically.

If [tex]f(x)=a(x^2)[/tex] when [tex]0<a<1[/tex], then it is compresed vertically.

If [tex]f(x)=(ax)^2[/tex] when [tex]0<a<1[/tex], then it is stretched horizontally.

If [tex]f(x)=(ax)^2[/tex] when [tex]a>1[/tex], then it is compresed horizontally.

In this case for [tex]g(x)=\frac{2}{5}x^2[/tex], it has the form [tex]f(x)=a(x^2)[/tex] and [tex]0<a<1[/tex], then the graph of g(x) is the graph of f(x) compresed vertically.

The graphs of the functions f(x) = x^2 and g(x) = 2/5x^2 both represent parabolas, with g(x) being vertically compressed by a factor of 2/5 compared to f(x), which makes the g(x) graph appear narrower and less steep than the f(x) graph.

The functions f(x) = x2 and g(x) = 2/5x2 both represent parabolas, which are U-shaped curves on a graph. The significant difference between these two functions is their scaling, or how they stretch or compress vertically. The function f(x) = x2 has no scaling factor, which means it represents a standard square function with a one-to-one ratio. On the other hand, the function g(x) = 2/5x2 has a scaling factor of 2/5, meaning the graph of g(x) compared to f(x), will be vertically compressed by a factor of 2/5. This means the heights on the graph of g(x) are 2/5 times the corresponding heights on the graph of f(x). Therefore, the g(x) graph will appear narrower and less steep than the f(x) graph.

Step-by-step explanation:

[tex](16+5i)+(6-7i)=16+5i+6+7i\qquad\text{combine like terms}\\\\=(16+6)+(5i-7i)=22-2i[/tex]

Answer:

22-2i

Explanation:

16+6=22

5i-7i=-2i

The volume is (area of cross-section) x (length) .

-- The cross-section is a triangle.  The area of a triangle is

Area = (1/2) (base) (height) .

In this one, the base is 9/4 m and the height is 3-1/3 m .

Area = (1/2) (9/4 m) (3-1/3 m)

Area = (1/2) (9/4) (10/3)

Area = 90/24 m² .

-- Volume = (area of cross-section) x (length)

Volume = (90/24 m²) x (7-1/3 m)

Volume = (90/24) x (22/3) m³

Volume = (1,980 / 72) m³

Volume = 27.5 m³

Answer:

The measure of angle B is [tex]132\°[/tex]

Step-by-step explanation:

step 1

Find the value of x

we know that

In an inscribed quadrilateral, opposite angles are supplementary

so

[tex]x\°+(2x+36)\°=180\°[/tex]

[tex]3x=180\°-36\°[/tex]

[tex]3x=144\°[/tex]

[tex]x=48\°[/tex]

step 2

Find the measure of angle B

[tex]B=(2x+36)\°[/tex]

[tex]B=(2(48)+36)\°=132\°[/tex]

Slope-intercept form: y= mx + b (m is the slope, b is the y-intercept or the y value when x = 0 ---> (0, y))

To find the slope, use the slope formula and plug in 2 points:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

(x₁ , y₁) = (5, 2)

(x₂ , y₂) = (10, 6)

[tex]m=\frac{6-2}{10-5} =\frac{4}{5}[/tex]

[tex]y=\frac{4}{5}x+b[/tex]    To find b, plug in a point into the equation (5, 2)

[tex]2=\frac{4}{5}(5)+b[/tex]

2 = 4 + b

-2 = b

[tex]y=\frac{4}{5}x -2[/tex]

Answer:

y = 4/5x -2

Step-by-step explanation:

equation of a line passing through two points is given by

y - y₁ = m (x - x₁), where m = (y₂ - y₁) / (x₂ - x₁)

y₂ = 6, y₁ = 2

x₂ = 10, x₁ =5

m = (6-2)/(10-5)

m = 4/5

y - 2 = 4/5 (x - 5)

multiply both sides by 5

5(y -2) = 4(x - 5)

5y -10 = 4x -20

5y = 4x -20 +10

5y = 4x -10

divide through by 5

y =4/5x -2

Step-by-step explanation:

The equation of a circle in standard form is

where (h, k) are the coordinates of the centre and r is the radius

here (h, k) = (- 6, 2) and r = 5[tex]\sqrt{3}[/tex], hence

(x - (- 6))² + (y - 2)² = (5[tex]\sqrt{3}[/tex] )², that is

(x + 6)² + (y - 2)² = 75

The statement that is always true is that supplementary and complementary angles are always adjacent angles.

The statement that is ALWAYS TRUE is (C) Supplementary and Complementary angles are always adjacent angles. Supplementary angles are two angles that add up to 180 degrees, while complementary angles are two angles that add up to 90 degrees. Adjacent angles are two angles that have a common vertex and a common side between them. So, it is always true that supplementary and complementary angles are adjacent angles because they share a common side.

ANSWER

[tex]y = \sqrt[3]{x + 4} - 1[/tex]

EXPLANATION

The given function is

[tex]y = \sqrt[3]{x} [/tex]

The transformation

[tex]y = \sqrt[3]{x + k} - c[/tex]

shifts the graph of the base function k units left and c units down.

Since the graph is shifted 4 units left, k= 4

Also, the graph is shifted 1 unit down.

This implies that c=1

Answer:  [tex]y-7=-\frac{1}{4}(x+5)[/tex]

Step-by-step explanation:

The equation of the line in Point-Slope form is:

[tex]y-y_1=m(x-x_1)[/tex]

Where "m" is the slope and ([tex]x_1,y_1[/tex]) is a point on the line.

You can identify that in the equation of the line [tex]y-3=4(x+2)[/tex], the slope is:

[tex]m=4[/tex]

By definition, the slopes of perpendicular lines are negative reciprocals. Then, the slope of the other line is:

[tex]m=-\frac{1}{4}[/tex]

 Finally, knowing that this line passes through the point (-5, 7),you can substitute this point and the slope into the equation  [tex]y-y_1=m(x-x_1)[/tex] to get the equation of this line:

 [tex]y-7=-\frac{1}{4}(x-(-5))[/tex]

 [tex]y-7=-\frac{1}{4}(x+5)[/tex]

a=5, b=-2

Step-by-step explanation:

If you simplify the equation, you get:

3ax +6 -4x -4b - 11x - 14 = 0 =>

3ax - 15x -4b -8 = 0

group together x's and constants:

(3a-15)x -8 -4b = 0

To make this 0 for all x, we have to find an a such that 3a-15 = 0 and b such that -8-4b = 0. this leads to a=5, b=-2

Answer: 1

Step-by-step explanation:

8 likes playing soccer

6 likes swimming

2 likes both

So in other words, because the 2 students likes swimming and playing soccer, they must be coming from the combined number of students (8+6=14) leaving only 1 who doesn't like to play either swimming/soccer.

There are 3 students who do not like either playing soccer or swimming and it can be determined by using set operation.

Given that,

In a class, there are 15 students. 8 of them like playing soccer, 6 of them like swimming, and 2 like both and swimming and playing soccer.

We have to determine,

How many students do not like either playing soccer or swimming?

According to the question,

Let x be the number of students who do not like either playing soccer or swimming.

Total number of students = n(U) = 15

Number of students who like playing soccer = n(A) = 8

Number of students who like swimming = n(B) = 6

Then,

The number of students like both = 2

Number of students who like swimming = Total number of students who like swimming - number of students like both

Number of students who like swimming  = 6 -2 = 4

And Number of students who like playing soccer = Total number of students who like playing soccer - number of students like both

Number of students who like swimming  = 8 -2 = 6

Therefore,

The total number of students = Number of students who like swimming + Number of students who like swimming + Number of students who do not like either playing soccer or swimming.

[tex]\rm 15 = (8-2) + (6-2) + x +2\\\\15 = 6+4+x+2\\\\15 = 12+x\\\\x = 15-12\\\\x=3[/tex]

Hence, there are 3 students who do not like either playing soccer or swimming.

AB=30×4+30=150

Answer:

150°

Step-by-step explanation:

The angle at the centre subtended by arc AB is twice the inscribed angle, that is

30x + 30 = 2(20x - 5) ← distribute

30x + 30 = 40x - 10 ( subtract 40x from both sides )

- 10x + 30 = - 10 ( subtract 30 from both sides )

- 10x = - 40 ( divide both sides by - 10 )

x = 4

Hence

arc AB = (30 × 4) + 30 = 120 + 30 = 150°
