Answer:
[−5,5]
Step-by-step explanation:
G(-3) = 2x - 2 Plug in -3 for x
= 2(-3) - 2 Multiply
= -6 - 2 Subtract
= -8
X = first film....y = second film
x + y = 132
x = 2y - 3
2y - 3 + y = 132
3y - 3 = 132
3y = 132 + 3
3y = 135
y = 135/3
y = 45......so the 2nd film lasted 45 minutes
x = 2y - 3
x = 2(45) - 3
x = 90 - 3
x = 87 <=== the first film lasted 87 minutes
Convert to same so it would be 9/12-1/12 9-1=8 so it would be 8/12 and you simplify that to get 2/3 more wool
