Why might you need to use the addition or subtraction property of equality more than once after you have used the distributive property and combined like terms? Explain.

Use the properties of equality and the distributive property to solve equations ... Although multi-step equations take more time and more operations, they can still be ... First “undo” the addition and subtraction, and then “undo” the multiplication and ... We need to “move” one of the variable terms in order to solve the equation.

Step-by-step explanation:

  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).
