The correct answer is a.
You can find this by using each of the ordered pairs in the equation and seeing if the statements are true. The work for the a ordered pairs is below.
(-2, -14)
y = 7x
-14 = 7(-2)
-14 = -14
(3, 21)
y = 7x
21 = 7(3)
21 = 21
(-4, -28)
y = 7x
-28 = 7(-4)
-28 = -28
A. 2s+s+1/2s+9=65
B. 3.5s+9=65
C. Subtract 9 from both sides to get: 3.5s=56 and then divide both sides by 3.5 to get s (the cost of the shirt) which is s=16
D. Shoes cost $32, shirt costs $16, and the sunglasses cost $8
Answer:
D
Step-by-step explanation:
we can set up the equation as 15x = 15x^2
factoring we get
15x(x-1) = 0
So the solutions are when x are 0 and 1
this gives the coordinates
(0,0) and (1,15)
