f(x)=8−4x−x3 g(x)=x2+7x−9 Find f(x)+g(x). Select one: a. x3+x2+3x−1 b. −x3+x+3x−1 c. −x3+x2+11x−9 d. 8x2+3x−9x3
vovangra [49]

Answer:

B

Step-by-step explanation:

We are given the two functions:

f(x) = 8 - 4x - x^3\text{ and } g(x) = x^2 + 7x - 9

And we want to find:

f(x) + g(x)

Substitute:

= (8 - 4x - x^3) + (x^2 + 7x - 9)

Rewrite:

= (-x^3) + (x^2) + (7x - 4x) + (8 - 9)

Combine like terms:

= -x^3 + x^2 +3x -1

In conclusion:

f(x) + g(x) =  -x^3 + x^2 +3x -1

Hence, our answer is B.

a factory manufactures a metal piece in 32 minutes now technology allowed the factory to cut the time by 8% then another Improve
aliya0001 [1]

Answer:

28 minutes

Step-by-step explanation:

First you have to find what 8% off of 32 is

If you take away 8% of 100% you have 92%

In order to find 92% of 32 you must divide 92 by 100 and multiply it by 32

.92 x 32 = 29.44

Then you have to take off another 5%

Of you take 5% off of 100% you have 95%

.95 x 29.44 =27.97

Then round to the nearest minute

28 minutes
