To find the zeros of f(x), equate f(x) to zero, that is
x(x - 2)(x + 6) = 0
Equate each factor to zero and solve for x
x = 0
x - 2 = 0 ⇒ x = 2
x + 6 = 0 ⇒ x = - 6

What is the slope of the line with the equation 3y+5x=4
Question 4 options:
-5
−53
35
3
I think none of these are right. It's Y=-5/3x +4/3
ANSWER
[tex] - \frac{5}{3} [/tex]
EXPLANATION
The given line has equation
[tex]3y + 5x = 4[/tex]
Rewrite the equation in the form:
[tex]y = mx + b[/tex]
Add -5x to both sides.
[tex]3y + 5x - 5x = - 5x + 4[/tex]
[tex]3y = - 5x + 4[/tex]
Divide through by 3.
[tex]y = - \frac{5}{3}x + \frac{4}{3} [/tex]
Comparing to the slope intercept formula,
[tex]m = - \frac{5}{3} [/tex]
The slope is
[tex] - \frac{5}{3} [/tex]

what’s the area
A. 64
B. 44
C. 30.25
D. 13.75
Answer:
B) 44
Step-by-step explanation:
Let's start with the triangles. Normally, when dealing with triangles, you would use the formula (B*H*1/2), but since there's two identical triangles, we can just do (B*H) and get the area for both:
2.5*5.5=13.75
Then to solve for the square, it is also (B*H):
5.5*5.5=30.25
At this point, to solve for the total area, you just add the areas together:
13.75+30.25=44
Hope this helps!
Answer: B. 44
Step-by-step explanation: The area of a rhombus is base times height. The height is 5.5 cm, and the base is 8 cm. To find the base, add 2.5 and 5.5.
8 x 5.5 = 44
The area is 44 cm^2

What is the Slope and y intercept
Answer:
The slope is .075 and the y intercept is -.125
Step-by-step explanation:
8y = .2(3x -5)
Distribute the .2
8y = .6x - 1
Divide by 8
8y/8 = .6x/8 -1/8
y = .075x -.125
This is in slope intercept form y= mx+b where m is the slope and b is the y intercept.
The slope is .075 and the y intercept is -.125
Find the missing part. l = 8, w = 4, h = 2 Find the diagonal (d) of the base.
pythagoras
a^2 = b^2 + c^2
a^2 = (8)^2 + (4)^2
a^2 = 64 + 16
a^2 = 80
[tex]a = \sqrt{80} [/tex]
Answer:
The length of the diagonal (d) = 4[tex]\sqrt{5}[/tex] units.
Step-by-step explanation:
We are given the length (l) = 8, width (w) = 4 and height (h) = 2.
Now we have to find the diagonal of the base.
The given figure is a rectangle box. The base of the rectangular box is a rectangle with the length (l) = 8 and the width(w) = 4
The length of the diagonal (d) = [tex]\sqrt{l^2 + w^2}[/tex]
d = [tex]\sqrt{8^2 + 4^2}[/tex]
d = [tex]\sqrt{64 + 16}[/tex]
d = [tex]\sqrt{80}[/tex]
d = [tex]\sqrt{16} \sqrt{5}[/tex]
d = 4[tex]\sqrt{5}[/tex]
So, the length of the diagonal (d) = 4[tex]\sqrt{5}[/tex] units.

Which of the following is the solution to the following system of inequalities? Let the green region represent the solution set. X+2y<=4 3x-y>2
Answer:
See picture attached.
Step-by-step explanation:
To find the solution, graph each equation using the y = mx + b form.
Start by converting to this form.
x + 2y < 4 becomes y < -1/2x +2
3x - y > 2 becomes y < 3x - 2
Then mark each y-intercept. These points are (0,2) and (0,-2).
Using the slope mark the next points at (-1,4) and (1, -1) respectively.
Connect using dash lines since this is not equal to in either inequality.
Test a point no on either line like (-1,-1).
If the inequality holds true, shade the area.
Where the areas overlap is the solution. See picture.
Inequalities are used to represent unequal expressions.
The solution to the inequality is [tex]x \le \frac 87[/tex] and [tex]y < \frac{10}7[/tex]
The inequalities are given as:
[tex]x + 2y \le 4[/tex]
[tex]3x - y > 2[/tex]
Express both inequalities as equations'
[tex]x + 2y = 4[/tex]
[tex]3x -y = 2[/tex]
Make y the subject in [tex]3x -y = 2[/tex]
[tex]y = 3x - 2[/tex]
Substitute [tex]y = 3x - 2[/tex] in [tex]x + 2y \le 4[/tex]
[tex]x + 2(3x - 2) \le 4[/tex]
Open brackets
[tex]x + 6x - 4 \le 4[/tex]
[tex]7x - 4 \le 4[/tex]
Collect like terms
[tex]7x \le 4+4[/tex]
[tex]7x \le 8[/tex]
Divide both sides by 7
[tex]x \le \frac 87[/tex]
Substitute 8/7 for x in [tex]3x - y > 2[/tex]
[tex]3 \times \frac 87 - y > 2[/tex]
[tex]\frac{24}7 - y > 2[/tex]
Collect like terms
[tex]- y > 2 -\frac{24}7[/tex]
Take LCM
[tex]- y > \frac{14 -24}7[/tex]
[tex]- y > \frac{-10}7[/tex]
Divide both sides by -1
[tex]y < \frac{10}7[/tex]

Another factor of 6, besides 6 and 1, is 3. Factors are numbers that divide into another number without leaving any remainder. Both 2 and 3 are factors of 6 since 2 multiplied by 3 equals 6.
Besides 6 and 1, another factor of 6 is 3.
Factors are whole numbers that divide evenly into another number. For the number 6, the factors are 1, 2, 3, and 6. The process of factoring involves finding all numbers that you can multiply together to get the number in question. In this case, 2 multiplied by 3 equals 6.
We can also verify this by noting that dividing 6 by 3 gives us 2 with no remainder, confirming that 3 is indeed a factor of 6.
convert 84 inches to yards
Answer:
The answer is 2.333 yards
Step-by-step explanation:
In every one yard there's thirty-six inches.
84/36= 2.333
Hope this helps :)
To convert 84 inches to yards, first convert inches to feet by dividing by 12, resulting in 7 feet. Then, convert feet to yards by dividing by 3, resulting in approximately 2.33 yards.
To convert 84 inches to yards, we need to use the relationships between inches, feet, and yards.
Start by converting inches to feet, and then convert feet to yards.
1. Convert inches to feet:
There are 12 inches in a foot, so divide the number of inches by 12.
84 ÷ 12
= 7 feet
2. Convert feet to yards:
There are 3 feet in a yard, so divide the number of feet by 3.
7 ÷ 3
= 2.33 yards
Thus, 84 inches is equal to approximately 2.33 yards.

Solve for x. |x| – 5 = 7
Answer:
x = 12Step-by-step explanation:
x - 5 = 7
⇒ x = 7 + 5 = 12
To solve for x, add 5 to both sides of the equation and then determine the absolute value of x.
Explanation:To solve for x in the equation |x| – 5 = 7, we need to isolate x on the left side of the equation. To do this, we can add 5 to both sides:
|x| – 5 + 5 = 7 + 5
|x| = 12
Now, we have an absolute value equation. The absolute value of a number is its distance from zero. Therefore, we have two possible solutions: x = 12 or x = -12.

[tex]P=(-5,-\frac{\pi}{6}+(2n+1)\pi)[/tex]
Therefore correct option is B.

The bases of a trapezoid are 20 and 32 feet. The height of the trapezoid is 6 feet
Answer:
The Answer is 156
Step-by-step explanation:
A=(B1+B2)H/2
1) to find the area of a trapezoid you must First add the 2 bases
20+32= 52
2) Then Multiply the 2 bases sum by the Height
52 x 6 = 312
3) divide the product 312 By 2
312/2= 156
That is Your answer!
Hopes this helps!
For the area of a trapezoid use formula: Area = (BaseX+BaseY) times Height divided by 2.
so for this problem you’d plug in (20+32) times 6 then divide it by two.
20+32=52 times 6 equals 312
Divide by 2 and you get 156.
Area= 156

A circle is centered at the point -3 2 and passes through the point 1 and 5 the radius of the circle is blank units
Answer:
The radius of the circle is 5 units
Step-by-step explanation:
Given in the question,
centered point = (-3 , 2)
a point in the circle = (1,5)
To find the radius of circle we will use the circle equation
(x – h)² + (y – k)² = r²,
with the centre being at the point (h, k) and the radius being r.
Plug values in the equation
(1 – (-3))² + (5 – 2)² = r²
(1+3)² + (3)² = r²
4² + 3² = r²
25 = r²
r = √25
r = 5

the table shows how much jake charged for the last 4 orders of pup cakes. what is the constant of proportionality in cost per pup cake?
Answer:
$2.50
Step-by-step explanation:
Let's take a look at the 4 orders and check the price per pup cake in each order:
Order 1: $5 for 2 cakes, so $2.50 per cake.
Order 2: $7.50 for 3 cakes, so $2.50 per cake.
Order 3: $12.50 for 5 cakes, so $2.50 per cake.
Order 4: $20.00 for 8 cakes, so $2.50 per cake.
Jake has a very consistent pricing of his cakes... they're always $2.50 each.
That price is the relation between the price asked and the number of cakes sold, that's the constant of proportionality in this case.
Answer:
Option 3rd is correct
$2.5 is the constant of proportionality in cost per pup cake
Step-by-step explanation:
The direct proportionality states that:
[tex]y \propto x[/tex]
then the equation is in the form of :
[tex]y = kx[/tex] ....[1]
where, k is the constant of proportionality.
As per the statement:
The table shows how much Jake charged for the last 4 orders of pup cakes.
Let y represents the cost and x represents the pup-cakes
Consider any values of x and y from the given tables.
x = 3 and y = $7.5
To find constant of proportionality in cost per pup cake.
Substitute these in [1] we have;
[tex]7.5 = 3k[/tex]
Divide both sides by 3 we have;
2.5 = k
or
k = 2.5
Therefore, $2.5 is the constant of proportionality in cost per pup cake
