Question 1 (Essay Worth 10 points) (04.02 MC)
A proportional relationship between the number of pounds of potatoes (x) and the price in dollars (y) is graphed, and the ordered pair (5, 4) is on the graphed line.
Part A: What is the price of 1 pound of potatoes? Show your work. (8 points)
Part B: What does the ordered pair (10,8) on the graph represent? Explain in words. (2 points)

the first one, all those points on the line just make a strait line.

its kind of blurry. can you put a clearer pic?

step-by-step explanation:

linear pair postulates

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
