Question:
The graph represents the two companies' prices. What is the linear equation that represents each T-shirt company?
Answer:
1.) Shirt Box: y = 7.5x + 30
2.) Just Tees: y = 10.5x
Step-by-step explanation:
For Number -<u>One</u>- We do - 7.5 + 30 = 37.5
For Number -<u>Two</u>- We do - 10.5 <u>×</u> "X"
You See We have to solve for "X"
This is just to give the idea, and Kinda help Explain it. . .
(Yes i know im 4 days late - & Yes i know its already answered, But I just explained it To get the Understanding of the Two answers.)
I think it would be greatest common factor
Factor the following:
x^2 - 5 x - 24
Hint: | Factor x^2 - 5 x - 24 by finding two numbers whose product is -24 and whose sum is -5.
The factors of -24 that sum to -5 are 3 and -8. So, x^2 - 5 x - 24 = (x + 3) (x - 8):
Answer: (x + 3) (x - 8)

Factor the following:
49 x^2 - 64
Hint: | Express 49 x^2 - 64 as a difference of squares.
49 x^2 - 64 = (7 x)^2 - 8^2:
(7 x)^2 - 8^2
Hint: | Factor the difference of two squares.
Factor the difference of two squares. (7 x)^2 - 8^2 = (7 x - 8) (7 x + 8):
Answer: (7 x - 8) (7 x + 8)

Factor the following:
x^2 - x - 110
Hint: | Factor x^2 - x - 110 by finding two numbers whose product is -110 and whose sum is -1.
The factors of -110 that sum to -1 are 10 and -11. So, x^2 - x - 110 = (x + 10) (x - 11):
Answer: (x + 10) (x - 11)___________________________________________________________
Factor the following:
49 x^2 - 64
Hint: | Express 49 x^2 - 64 as a difference of squares.
49 x^2 - 64 = (7 x)^2 - 8^2:
(7 x)^2 - 8^2
Hint: | Factor the difference of two squares.
Factor the difference of two squares. (7 x)^2 - 8^2 = (7 x - 8) (7 x + 8):
Answer: (7 x - 8) (7 x + 8)

Factor the following:
25 x^2 + 40 x - 10
Hint: | Factor out the greatest common divisor of the coefficients of 25 x^2 + 40 x - 10.
Factor 5 out of 25 x^2 + 40 x - 10:
Answer: 5 (5 x^2 + 8 x - 2)

Factor the following:
9 x^2 + 3 x^2 - 6 x
Hint: | Add like terms in 9 x^2 + 3 x^2 - 6 x.
3 x^2 + 9 x^2 = 12 x^2:
12 x^2 - 6 x
Hint: | Factor common terms out of 12 x^2 - 6 x.
Factor 6 x out of 12 x^2 - 6 x:
Answer: 6 x (2 x - 1)
Answer:
The answer for #13 should be y= -2x+3
The answer for #14 should be y= 1/2x+10
The answer for #15 should be y= -1/10x+70
The answer for #16 should be y= 1/2x-6
The answer for #17 should be y= 5x+2
And the answer for #18 should be y= 12x+7
Hope I helped :)

Answer:
Step-by-step explanation:
y - 4 = -2/3(x - 3)
y - 4 = -2/3x + 2
y = -2/3x + 6
