The answer is A I believe.
At hour 1, the equation must equal 130,
therefore s(1) = 9(1-1) + 130
s(1) = 9(0) + 130
s(1) = 130
then so on when
s(2) = 9(2-1) + 130
s(2) = 139
14+ 13y - 13y = 20y - 13y -21 (taking away the smallest y value from both sides)
14 = 7y - 21
14 + 21 = 7y - 21 +21 (+21 on both sides to remove -21 if we do -14 then we will have nothing on other side)
35 = 7y
35/7 = 7y/7 (dividing 7 on both sides)
5 = y
answer is 100% correct no doubts. hope it helped you.
Answer:
I believe it is -3, althought -9 would work it needs to be simplified as low as possible and 3x3=9, therefore you can simplify 9 to 3.
