4(-2x-5)+8=8x+4 what is the value of x

First, you need to distribute the four to the -2x and the -5. you end up with -8x-20. you add 8 to your -20 and get -12. now your equation reads -8x-12=8x+4. you want to find x so you have to isolate it. you add 8x to both sides and then subtract 4 from both sides. now your equation is -16=16x. you divide both sides by 16 and you get x=-1

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

answer: the function g(x) has the greatest slope.
