714/12
= 59.5
The lamp manufacturer uses 59 and a half spools of electrical cord. If you round to the nearest whole number, he uses about 60 spools of cord.

divide 714 by 12

714 / 12 = 59.5 spools per week

Find the inverse of the given function
xenn [34]

For this case, we must find the inverse of the following function:

f (x) = \frac {5x + 1} {- x + 7}\\x\neq 7

To find the inverse we follow the steps below:

y = \frac {5x + 1} {- x + 7}

We rewrite the denominator:

y = \frac {5x + 1} {- (x-7)}\\y = - \frac {5x + 1} {(x-7)}

We exchange variables:

x = - \frac{5y + 1} {(y-7)}

We solve for y:

We multiply on both sides of the equation by (y-7)

x (y-7) = - 5y-1\\xy-7x = -5y-1

We subtract xy on both sides of the equation:

-7x = -5y-1-xy

We add 1 to both sides:

-7x + 1 = -5y-xy

We factor for y:

-7x + 1 = y (-5-x)

We divide both sides by (-5-x):

y = \frac {-7x + 1} {- 5-x}

So, we have:

f ^ {- 1} (x) = \frac {-7x + 1} {- 5-x}

Answer:

f ^ {- 1} (x) = \frac {-7x + 1} {- 5-x}

x\neq -5

Directions: Simplify each term by factoring.
zheka24 [161]

Answer/Step-by-step explanation:

[1] 3rs = 3 * r *s

[2] 12xy = 2*2*3*x*y

[3] 5x^2=5*x*x              

[4] 36x^2=2*2*3*3*x*x

[5] 25^2=5*5*x*x

[6] 30x^2=2*3*5*x*x

[7] 5x^3=5*x*x*x

[8] 24y^3=2*2*2*3*y*y*y

[9] 9xy=3*3*x*y

[10] 12x^4=2*2*3*x*x*x*x

Factoring means to factor a number means to break it up into numbers that can be multiplied together to get the original number.

Change 239 to a common fraction or mixed number and express it in its simplest form
Evgen [1.6K]
If this is suppose to be 239%....

change to a fraction to look like this 238/100. This number cannot be reduced, so the common fraction is 239/100.

to make it a mixed number, you would simply divide 239 by 100. Your answer would come out to 2 with a remainder of 39. Put the remainder over the divisor and your answer for a mixed number will be 2 and 39/100.<span />
