Answer: x=12-y
2x+2y=24
2x=24-2y
x=12-y
Answer:
Step-by-step explanation:
Y = x² - 2x + 5
x = -2
y = -2² -2(-2) + 5
y = 4 + 4 + 5 = 13
x = -1
y = -1² -2(-1) + 5
y = 1 + 2 + 5 = 8
x = 1
y = 1² -2(1) + 5
y = 1 - 2 + 5 = 4
x = 3
y = 3² -2(3) + 5
y = 9 - 6 + 5 = 8
x = 6
y = 6² -2(6) + 5
y = 36 - 12 + 5 = 29
The answer is $2.7 per gallon
