F(x) = 3x - 5x + 40: f(2).

f(2) = 36

Step-by-step explanation:

Hello!

To find f(x), plug in 2 for x in the original equation.

Solve:

The final solution is 36.

Y = 36   or  F = -x+20

^ ^ ^ Not sure about what ur asking, so I put in 2 versions that I know of.

Step-by-step explanation:

Write out the equation:

f(2) = 3x - 5x + 40

If X is 2, then write the equation out as:

Y = 3(2) - 5(2) + 40

Now multiply:

Y = 6 - 10 + 40

Simplify:

Y = 36

Let's solve for f.

f(2)=3x−5x+40

Divide both sides by 2.

2f/2 = −2x+40/2

f=−x+20

f=−x+20

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer
