Whats the Value of X?

10

Step-by-step explanation:

The way you can find this is by thinking about x+15 being equal to 25 so you would write the equation like this.  

x+15= 25

 -15    -15

x=10

So the value of x is 10

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
