Angel was in charge of ordering graphic T-shirts for the craft fair. The graph shows the relationship between the number of boxes of T-shirts Angel ordered x and the total number of T-shirts y. 1. Is the relationship in the graph a proportional relationship? Explain how you know. 2. What is the constant of proportionality? How do you know based on the graph? 3. Write an equation to represent the relationship

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.

it would rotate about 180 degrees.

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
