What is the value of f(x) = 9x when x = -2?

 The required value of f(x) when x = -2 is -18.

Step-by-step explanation:  We are given to find the value of f(x) when x = -2 where f(x) is defined as follows :

To find the required value, we must substitute x = -2 in equation (i).

So, putting x = -2 in equation (i), we get

Thus, the required value of f(x) when x = -2 is -18.

answer:

it will cost 480 dollars to refurbish the larger wood floor

step-by-step explanation:

as it's a ratio of 4 that costs 384 dollars, divide the price by the ratio

384 / 4 = 96 dollars

96 dollars per unit of the ratio

now to get the price to refurbish the larger wood floor, times the price by the units

96 * 5 = 480

50=33x+22
