Chad and Eric left a 20% tip after having lunch at a restaurant. Chad's lunch cost $10. Which equation can you use to find x, the cost of Eric's lunch?

Group of answer choices

A) 0.2(x + 10) = 5

B) 0.2x = 10 + 5

C) 0.2x + 5 = 10

D) 0.2x + 10 = 5

step-by-step explanation:

55

step-by-step explanation:

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
