You eam (4x + 12) points after completing x levels of a video game and
then lose (2x - 5) points. write an expression that represents the total
number of points you have now

(4x+12) - (2x-5)

Step-by-step explanation: The (4x+12) is positive and the (2x-5) is negative.

step-by-step explanation:

mean or average is 40.6

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
