The slopes of perpendicular line segments are start fraction one over three end fraction and start fraction d over five end fraction. what is the value of d?

d = -15

Step-by-step explanation:

The slopes of perpendicular lines have a product of -1.

1/3·d/5 = -1

d/15 = -1 . . . . simplify

d = -15 . . . . . multiply by 15

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
