a line has this equation y=-1/2x+5 what is the equation for the perpendicular line that goes through (10,3)

Y=2x-17

Step-by-step explanation:

If a line is perpendicular it means their slope is reciprocal to each other.

Y=-1/2X+5 has a slope of -1/2

The function that is perpendicular will have a slope of 2.

Y=2x+b

Plug in(10,3)

2(10)+b=3

b=-17

Y=2x-17

your answer would be b

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
