Answer:
I'm not sure, but is it 2?
Step-by-step explanation:
12
4y - 2x
= 4(7) - 2(8)
= 28 - 16
= 12
I do not see a image
you would just 4.8 x how many years
285
just figure out how many is made then multiple that by 15
18
f(x) = 2x^2
Let x = -3
f(-3) = 2 * (-3)^2
Exponents first
f(-3)=2 *9
f(3) = 18
