If f(x) = 16x – 30 and g(x) = 14x – 6, for which value of x does (f – g)(x) = 0? –18 –12 12 18

Option 3: 12 is the correct answer.

Step-by-step explanation:

Given functions are:

In order to find the value of x on which (f-g)(x) will be zero, first of all we have to find (f-g)(x) and then equate it equal to zero to find the value of  that will make (f-g)(x)

So,

Now to find the value of x on which (f-g)(x) will be zero, putting (f-g)(x) = 0

Adding 24 on both sides

Dividing both sides by 2

For x=12, (f-g)(x) will be zero.

Hence,

Option 3: 12 is the correct answer.

step-by-step explanation:

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x
