Answer:
-9
Step-by-step explanation:
You have to plug 8 into the formula for x. f(8) = -2(8)+7 = -16+7 = -9
To solve this question, first cross multiply
Let ? = x
4/9 = x/81
4(81) = 9(x)
Simplify.
81 x 4 = 324
324 = 9x
Isolate the x, divide 9 from both sides
324/9 = 9x/9
x = 324/9
x = 36
4/9 = 36/81
36 is your answer
