Acliff on the seashore os eroding at a rate of 17 centimeters per year. write and solve an equation to find the number of years in which the cliff will erode 85 centimeters.

it would open into a square depending on the type of envelope i’m not sure about the second part

graph them on a graphing calculator, press 2nd trace. select intersect. hit enter until it says answer. ti 84 works best

step-by-step explanation:

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

the area of ​​the surface of the rectangular prism here is 250 cm2, which is the surface of the shading
