A. Coefficient of Variation
Answer: X=7
Step-by-step explanation:Let's solve your equation step-by-step.
3x+8−x=4−2x+32
Step 1: Simplify both sides of the equation.
3x+8−x=4−2x+32
3x+8+−x=4+−2x+32
(3x+−x)+(8)=(−2x)+(4+32)(Combine Like Terms)
2x+8=−2x+36
2x+8=−2x+36
Step 2: Add 2x to both sides.
2x+8+2x=−2x+36+2x
4x+8=36
Step 3: Subtract 8 from both sides.
4x+8−8=36−8
4x=28
Step 4: Divide both sides by 4.
4x
=28
4x/4=x 28/4
=
28
/4=7
(f + g)(x) is equal to f(x) + g(x).
So (f + g)(x) = (3x + 5) + (-2x^2 - 5x + 3) = -2x^2 - 2x + 8
which is choice C.
