1. A number subtracted from 8 is the same as the sum of 3 times a number and 4. What is the number?

Number = -1

Step-by-step explanation:

8 - x = 3(x + 4)

8 - x = 3x + 12 ( /+x / -12 on both sides)

8 - 12 - x + x =  3x + x + 12 - 12

-4 = 4x (/ divide by 4)

-4/4 = 4x/4

-1 = x

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
