Step-by-step explanation:

The slope of a perpendicular line to the another one is the opposite reciprocal of the original line.

The slope of the line in this case using (y1-y2)/(x1-x2) is (3-2)/(0-3) which tells us the slope of the given line is -1/3.

Taking the opposite reciprocal means means to switch the top and bottom and switch the sign. So you get that the slope of the perpendicular line is 3.

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.

step-by-step explanation:

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
