These are not the exact numbers but just plug in the numbers of yours Because we know that q is a perpendicular line to p we know that its slope is the negative reciprocal of the slope of p. So its slope is 7/10. Now we just need to find its y-intercept. To do that we write what we know about line q. So we know that the equation for line q looks like:

y = (7/10)x + b

We also know that q passes through the point (8,7), so we now plug that in and solve for b:

7 = (7/10)(8) + b
7 - (56/10) = b
(70/10) - (56/10) = b
14/10 = 7/5 = b

So now that we have solved for the y-intercept, we know that the equation for line q is:

y = (7/10)x + 7/5

What is (f.g)(x)? f(x) = -2x + 3 g(x) = 2x Write your answer as a polynomial or a rational function in simplest form.​
Len [333]

Answer:

-4x +3

Step-by-step explanation:

Given the functions f(x) = -2x + 3 and g(x) = 2x We are to find the composite function (f*g(x))

(f*g(x)) = f(g(x))

f(g(x)) = f(2x)

f(2x) = -2(2x) + 3

f(2x) = -4x +3

Hence f(g(x)) = -4x +3
