Let f(x)=2x-1 and g(x)=1/x. Find the value of f(g(7))

netineya [11]

Answer:

-5/7

Step-by-step explanation:

We need to find g(7) first

All we have to is plug 7 in the place of x

g(7) = 1/7

Now we have f(1/7) = 2x - 1

f(1/7) = 2(1/7) - 1

f(1/7) = 2/7 - 1

Don't forget about common denominators

2/7 - 7/7 = -5/7

A translation along the vector (-2 , 7 ) maps point P to point Q. The coordinates of point Q are (4, -1 ) What are the coordinat

Artist 52 [7]

<span>A translation is simply a "moving" when it comes to a point. In this case, by adding (-2, 7) to the point P, we will find point Q. That is, x-2 gives Q's x-coordinate of 4 and y+7 gives Q's y-coordinate of -1. To start, x-2 = 4 gives an x of -6, and y+7 = -1 gives a y of -8. So, the original point P was located at (-6,-8).</span>
