What is the solution
2x+6=20

x = 13

Step-by-step explanation:

add 6 to both sides (6+6 and 6+20)

2x = 26

—- —— 26/2 is 13!

2 2

2

x=13

Step-by-step explanation:

2x+6=20                      First you add 6 from both sides.

     +6   +6        

2x= 26  

2          2              Then you have to divided both sides by 2 to get the x  alone.

x= 13 That is your answer

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
