A school raised &4,589 in a sale. Mr Simmons class raised 1/100 of the money. How much did Mr Simmons class raise?
Ksenya-84 [330]

Alright, lets get started.

total amount school raised in sale = $ 4589

Mr Simmons class raised \frac{1}{100} of the money.

So, if we want to find amount of the money Mr. Simmons raised, we sould take one hundered of the total amount.

Hence money raised by Mr. Simmons class = \frac{1}{100} * 4589

Hence money raised by Mr. Simmons class = \frac{4589}{100}

Hence money raised by Mr. Simmons class = $ 45.89 : Answer

Hope it will help :)

Let f(x)= x2 - 14 and g(x) = 6-X.<br> Find (fq)(7).
sleet_krkn [62]

Answer:

(fg)(7) = - 35

Step-by-step explanation:

The given functions are:

f(x) =  {x}^{2}  - 14

and

g(x) = 6 - x

We want to to find

(fg)(7)

Note that:

(fg)(x) = f(x) \times g(x)

We substitute the functions to obtain:

(fg)(x) = ( {x}^{2} -1 4 ) \times (6 - x)

We now substitute x=7, to get:

(fg)(7) = ( {7}^{2} -1 4 ) \times (6 - 7)

This implies that

(fg)(7) =( 49-1 4 ) \times (6 - 7)

(fg)(7)  = 35 \times  - 1 =  - 35

Whats the solutions for f(x)=- x^2-6x-8
poizon [28]

Answer:

x = -4, -2

Step-by-step explanation:

-x² - 6x - 8 = 0

x² + 6x + 8 = 0

x² + 4x + 2x + 8 = 0

x(x + 4) + 2(x + 4) = 0

(x + 4)(x + 2) = 0

x = -4, -2
