You bought 5 folders that cost x dollars each, a calculator for $45, and a set of pens for $3. a. 5x + 48 c. 5x + 45x + 3x b. 5 + 45 + 3

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

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
