A car backs up 12 feet, followed by 9 more feet. The car's position can be represented by the sum negative 12 plus left parenthesis negative 9 right parenthesis. Find the sum. Use pencil and paper. Represent the situation with a drawing. Superimpose a number line in the drawing to represent the situation in a third way.

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

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
