4.. Please help. Is DE←→ perpendicular to FG←→? Why or why not?

Given:

DE contains the points D(1, -2) and E(3, 4).

FG contains the points F(-1, 2) and G(4, 0).

To find:

Is DE perpendicular to FG.

Solution:

Slope of DE:

Here

m = 3

Slope of FG:

Here

Two lines are perpendicular if product their slopes are -1.

Slope of DE × Slope of FG

         ≠ -1

The solution is no, because the product of the slopes is not -1.

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17
