What is the slope of the line that passes through the points (-2, -5)(−2,−5) and (18, -5) ?(18,−5)? Write your answer in simplest form.

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15

x= 25/4.

is your answer.

i think you forgot some signs inbetween? if so comment and i'll try to

a magnifying glass is a convex lens which produces a magnified image of an object. for a magnified image to be observed the distance between the object and the lens has to be shorter than the focal length of the lens.
