Answer:

The answer to your question is:   (f +g)(x) = 2x² +x -11

Step-by-step explanation:

f(x) = 2x + 3

g(x) = x² + x/2 -7

Find (f+ g)(x)

                    (f+ g)(x) = 2(x² + x/2 -7) + 3    substitution

                     (f +g)(x) = 2x² +x -14 + 3        simplify like terms

                   (f +g)(x) = 2x² +x -11                 result

Someone help me on this math problem.
timofeeve [1]

If M is a midpoint of PQ, then we can use the formula of a midpoint:

\left(\dfrac{x_1+x_2}{2},\ \dfrac{y_1+y_2}{2}\right)

We have the endpoints (-2a, 0) and (0, 2b). Substitute:

\dfrac{-2a+0}{2}=\dfrac{-2a}{2}=-a\\\\\dfrac{0+2b}{2}=\dfrac{2b}{2}=b

<h3>Answer: M(-a, b)</h3>

12 workers build a wall in 10hours. How long do 5 workers build a wall​
snow_lady [41]

Answer:

24 hours

Step-by-step explanation:

If 12 workers take 10 hours to build a wall, assuming they build at the same rate, it would take one worker 120 hours to build a wall.

By this logic, it would take 120/5 or 24 hours for 5 workers to build a wall
