Answer

-1,11

step by step

when x =11

3|x-5|=20

3|11-5|+2=20

3|6|+2=20

18+2=20

20=20

when x=-1

3|-1-5|+2=20

3|-6|+2=20(the -6 became 6 due to | | sign)

3*6+2=20

18+2=20

20=20

2. Find the slope of the line that passes through the points A(0,2) and B(4,-1)

bogdanovich [222]

Answer:

Use the slope formula to find the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1), or the change in the y values over the change in the x values. The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2.
