On the real number line below, with coordinates as labeled, an object moves according to the following set of instructions: From point the object moves right to then left to then right to , and finally left until it returns to its original position at What is the closest estimate of the total length, in coordinate units, of the movements this object makes? A. 0 B. 4 C. 12 D. 22 E. 36

Please describe how to find the answer as well! I'm lost on how to solve this.

here is a big fat

hey there : ) your answer would be a.

step-by-step explanation:

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex

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
