Answer:
f(2) = 36
Step-by-step explanation:
Hello!
To find f(x), plug in 2 for x in the original equation.
Solve:
- f(x) = 3x - 5x + 40
- f(2) = 3(2) - 5(2) + 40
- f(2) = 6 - 10 + 40
- f(2) = -4 + 40
- f(2) = 36
The final solution is 36.
Answer:
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
Answer:
f=−x+20
