In a plane, line e is perpendicular to line f, line f is perpendicular to line g, and line h is parallel to line f. which of the following must be true?

a). line h is perpendicular to line g

Step-by-step explanation:

In these cases, always make a litle scetch, and just plot what is given.

You can immediately see the answer, which is answer a).

lf h is parallel to f and line f is perpendicular to line g,

then line h is perpendicular to line g.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
