The answer is that y is equal to -3 and x is equal to 7
2x-y=17
-2(x-y)=10 )
--------------
2x-y=17
-2x+2y=-20
----------------
y=-3
x-y=10
x-(-3)=10
x+3=10
-3 -3
----------
x=7

Answer:
The answer is A.
Step-by-step explanation:
The first graph was dilated by 1/2, therefore the answer is A
Answer:
B. The solution is valid because all steps to solve the inequality for F are correct.
Step-by-step explanation:
F - 32 ≤ 0
Add 32 to both sides of the equation to have;
F -32 + 32 ≤ 0 + 32
F ≤ 0 + 32
F ≤ 32
It can be observed that to solve for F, the steps are correct. Thus the solution is valid. Therefore, the correct choice in the given question is the solution is valid because all steps to solve the inequality for F are correct.
Answer:
The answer is B.
Step-by-step explanation:
