Evaluate ƒ(x) when x = -9.
a. no solution
b. 488
c. 12
d. 110

The answer to your question is: 12

Step-by-step explanation:

 You have a function with two conditions,

- the first condition do not consider number nine, because it uses the symbol <, then we can not evaluate nine in this function.

- the second condition considers nine because uses the symbol ≤ which means that nine is considered here, but the function equals 12, so that is the solution.

step-by-step explanation:

step 1: simplify both sides of the equation.

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
