One year, China consumed 4 times as much energy as Brazil. Define a variable and write an equation to find the amount of energy Brazil mused that year if China used 12,000 kilowatt-hours.

correct answers below:

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
