If f(x) = −5x − 4 and g(x) = -3x - 2, find (f+ g)(x).
SSSSS [86.1K]

Answer:

(f+g)(x) = -8x-6

Step-by-step explanation:

We are given the two functions:

\displaystyle f(x) = -5x - 4 \text{ and } g(x) = -3x - 2

And we want to find:

(f+g)(x)

Recall that this is equivalent to:


\displaystyle (f+g)(x) = f(x) + g(x)

Substitute and simplify:

\displaystyle \begin{aligned} (f+g)(x) &= (-5x-4)+(-3x-2) \\ \\ &= -8x-6 \end{aligned}

In conclusion:

(f+g)(x) = -8x-6

How much candy at $1.16 a pound should be mixed with candy worth 86 cent a pound in order to obtain a mixture of 60 pounds of ca
vovangra [49]
Let the weights of the two candies be repres. by x and y.

Then x + y = 60, or x = 60 - y

($1.16 / lb) x + ($0.86 / lb) y = ($1.00 / lb) (60 lb) = $60

Then 1.16(60-y) + 0.86y = 60
   69.6 - 1.16y + 0.86y = 60                                9.6
     9.6 = 0.3y                         Solving for y, y = ------- = 32 lb
                                                                            0.3

                                               Then x = (60-32) lb = 28 lb
