Question 7
#7) What value of m makes the equation true?
3(8 – m) = 5m – 40
Answers
Answer:
8
Step-by-step explanation:
3(8-m)=5m-40
you first distribute 3 through the parenthesis
24-3m=5m-40
Move the variable to the left and change sign
24-3m-5m=-40
now move the constant to the right
-3m-5m=-40-24
collect like terms
-8m=-40-24
-8m=-64
Divide both sides by -8 and negative divide negative number becomes positive
so m = 8
so I put your equation in cymath. feel free to use it whenever you need help. it really do comes in handy.

The surface area of one box is 62 square inches.
What is surface area of a cuboid?The surface area of a cuboid is the total space occupied by it. A cuboid is a six-faced three-dimensional shape in which each face is in the shape of a rectangle.
Given that, Yolanda makes wooden boxes for a crafts fair.
The dimensions of box are length= 5 inches, breadth = 3 inches and height = 2 inches.
We know that, the formula to find the toral surface area of cuboid is 2(lb+bh+hl)
Now, surface area = 2(5×3+3×2+2×5)
= 2(15+6+10)
= 2(31
= 62 square inches.
Therefore, the surface area of one box is 62 square inches.

Marco. Need to buy some cat food at the nearest store three bags of cat food cost $15.75 how much with Marcos me on five bags of cat
Answers
Answer:
$26.25
Step-by-step explanation:
We are told that Marco needs to buy some cat food. At the nearest store, 3 bags of cat food cost $15.75.
First of all we will find cost of 1 bag of cat food by dividing 15.75 by 3.
Now we will find the amount that Marco has spend for 5 bags of cat food by multiplying 5.25 by 5.
Therefore, Marco has spend $26.25 for purchasing 5 bags of cat food.
Answer:
5.25 per bag
Step-by-step explanation:
Just divide the amount of money by the number of bags needed.
15.75 divided by 3 = 5.25
0.4x-0.25=1.75

E.
The graph has zeros at x = -5 and x = -1.
F.
The graph represents the function f(x) = -x2 - 6x - 5.
Answers
Answer:
E
Step-by-step explanation:
The statements that are not true are:
The graph has a y-intercept at (0,5) is not true.
The graph has a relative maximum point (-3,4) is not true,
The graph has zeros at x = -5 and x = -1 is not true.
Options, A, B, and E are the correct answer.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
- The y-intercept can be found by setting x=0, which gives f(0)=-5.
So the y-intercept is (0,-5).
- To find the relative maximum,
We need to find the vertex of the parabola.
The x-coordinate of the vertex is given by -b/2a, where a=-1 and b=-6.
So, x=3 is the x-coordinate of the vertex.
To find the y-coordinate, we plug in x=3 into the function:
f(3) = -(3²) - 6 (3) - 5 = -32.
So the vertex is (3,-32), which is a relative minimum, not a maximum.
- To find the x-intercepts,
We set y =0 and solve for x.
-x² - 6x - 5 = 0.
Factoring or using the quadratic formula,
We get x = -5 and x = -1.
- The y-axis is a line of symmetry for any parabola of form f(x)=ax²,
f(-x) = a (-x)² = ax² = f(x).
- To find the zeros,
We set f(x) = 0 and solve for x.
-x² - 6x - 5 = 0.
Factoring or using the quadratic formula,
We get x = -5 and x = -1.
So the graph has zeros at x = -5 and x = -1, not x = -2 and x = 3.
- The graph represents the function f(x) = -x2 - 6x - 5.
The graph is true.
Thus,
The graph has a y-intercept at (0,5) is not true.
The graph has a relative maximum point (-3,4) is not true,
The graph has zeros at x = -5 and x = -1 is not true.

First you have to plot Bart's Garage's fee. Bart's equation is y = 30x + 20, so you would need to plot the points (0, 20) and (1, 50).
Lisa's base fee is the same, so her equation would have a + 20 at the end of it, but her hourly fee is higher. Therefore her hourly fee would be higher than 30. Her equation could be anything above 30, y = 50x +20 would work. The points for that graph are (0, 20) and (1, 70).

You have 8 cups of flour. It takes 1 cup of flour to make 24 cookies. The function C(f) = 24f represents the number of cookies, C, that can be made with f cups of flour. Which set of ordered pairs represent points on the graph of C(f) = 24f?
Answers
Answer:
c(0) = 24*0 = 0
c(8) = 24*8 = 192
Your range is [0,192]
Step-by-step explanation:
Answer:
You have 8 cups of flour it takes 1 cup of flour to make 24 cookies the function c(f)=24f
c represents the number of cookies
f represents the cups of flour
You have 8 cups of flour, we can use only 0 to 8 cups of flour.
so domain f is 0 to 8 cups [0,8]
Now we find the range
1 cup of flour to make 24 cookies
So 8 cups of flour = 24* 8 = 192 cookies
using 8 cups you can make 192 cookies
So number of cookies is from 0 to 192
Range is [0,192

John’s square garden has a perimeter of 26 ft. If John walks through the garden on the diagonal, how far did John walk? Round answer to the nearest tenth.
Answers
Answer:
9.19 ft
Step-by-step explanation:
Since it's a square, we know that all the sides are equal to 26/4 which equals 6.5. Then, we use the Pythagorean theorem to calculate the diagonal (since the diagonal is splitting the square into two right triangles). So we to a^2+b^2=c^2. So 42.25+42.25=84.5. The square root of 84.5 rounded to the nearest tenth is 9.19
