muminat

Answer:

Amount of gas = 3.2 gallons

Required coordinate pair is (3.2, 12)

Step-by-step explanation:

x=\frac{12}{3.75}

x=3.2\ gallon\ of\ gas

Therefore, Berto can buy 3.2 gallon of gas and required coordinate pair is (3.2, 12).

Whay is the value of g (-3l when g(x)= 2x-2
butalik [34]

Answer & Step-by-step explanation:

When you see g(x), then the number found in the place of x represents the value of x for that equation. So, the value of x for this equation is -3.

g(-3) = 2(-3) - 2

g(-3) = -6 - 2

g(-3) = -8

So, the value of g(-3) is -8
