Answer:
8x2−8xy−6y2
Step-by-step explanation:
if your answer choices contain exponents then of course the number behind the x's are exponents.
If you let x represent the number of free throws.
let y represent the number of two-point field goal.
let z represent the number of three-point shots made.
Then the correct system of linear equations is as follows:
x + 2y + 3z = 29 (The total number of points scored is 29.)
z = 3x - 29 (The number of 3-pointers was 29 less than 3 times the number of free throws.)
2y = z + 15 (Twice the number of 2-point shots made was 15 more than the number of 3-pointers.)
Solution:
This basketball player scored 10 points via free throws (10 at 1 point each), 16 points via 8 two-point shots made, and 3 points via 1 three-point shots made. So, in the choice its letter D.
<span>Let the variable A represent the number that goes in the blank.
-7y + 5(3 + Ay) = 3y + 15
-7y + 15 + 5Ay = 3y + 15
-7y + 5Ay = 3y
(-7 + 5A)y = 3y
-7 + 5A = 3
5A = 10
A = 2
Answer: D. 2
