To which of the following equations are x = -4 and x = -3 the only solutions?
O A. 71 – 12 = 12
OB. (r + 7) = -12
OC. (+ 7) = 12
OD. 3 + 41 = 2

correct answer was 0.5

shell's the art director at her local community center. she paid $10 and for each child that attends she earns $4.

for each child she ears $4 that is the slope m = 4

she paid $10, that is the initial amount paid. so 10 is the y intercept b

m =4   and b = 10

y intercept is 10 so the point is (0,10)

we start graph from y intercept (0,10)

slope = 4 . we know slope = rise / run

slope = 4   or 4/1   are same

rise = 4   and run = 1

for rise we move 4 units up and for run we move 1 unit to the right

the graph is attached below

x axis is the number of child she attends

y axis is the amount   she earns

i’m kinda new to precal but your answer should be 21. hope i got it right.
