A car backs up 12 feet, followed by 9 more feet. The car's position can be represented by the sum negative 12 plus left parenthesis negative 9 right parenthesis. Find the sum. Use pencil and paper. Represent the situation with a drawing. Superimpose a number line in the drawing to represent the situation in a third way.

is should be y = 5x

step-by-step explanation:

correct me if im wrong

x = 23.78

step-by-step explanation:

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
