Exercise 5 Page 246

Substitute each value of f one at a time into the equation to verify if it is true or false.

None

Practice makes perfect

We want to verify if any of the given values of f are solutions of this equation. We will replace the variable with each value from the set and check if the equation is true for any of them.

f	f-13.2=28.9	Simplify	True or False?
38.7	38.7-13.2? =28.9	25.5 ≠ 28.9	False
42.2	42.2-13.2? =28.9	29 ≠ 28.9	False
45.8	45.8-13.2? =28.9	32.6 ≠ 28.9	False
51.4	51.4-13.2? =28.9	38.2 ≠ 28.9	False

The equation is false for all of the given values. Therefore there is no solution to the equation out of the given values.
