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:

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.

Last year there were 1,435 8thgrade students enrolled at your school. This year there are 1,220. What is the percent change in t

julsineya [31]

Hi there!

Answer:

-14.98%(or -15%).

Step-by-step explanation:

1)To find the percent decrease,all you have to do is minus the original number from the decreased amount so:

1435-1220= 215

2)Then you divide this answer by the original number again so:

215÷1435= 0.1498

3)Then you times the decimal by 100 so:

0.1489x100= -14.98%(or -15%).

Hope this helps!

Step-by-step explanation:

Step 1: Define

-2(5x - 5.5) + 8 = -9x + 2 - (-5)

Step 2: Solve for x

Distribute: -10x + 11 + 8 = -9x + 2 + 5
Combine like terms: -10x + 19 = -9x + 7
Add 10x to both sides: 19 = x + 7
Subtract 7 on both sides: 12 = x
Rewrite: x = 12
