We'll the answer is x=4

How I found it:
1st I converted mixed numbers into improper fractions
2nd Multiplied both sides by 2
-(x+2)+3x=6
2x-2=6
then i added 2 to both sides
2x=8
then to get rid of 2 from x, i divided 2x/2=8/2
and then my answer became x=4
I hope this helps you out. Good Luck =)

Find the inverse function of f(x)= square root of 2x+2

Alik [6]

The inverse function of the above function is f(x) = $\frac{x^{2} - 2}{2}$

You can find the inverse of any function by switching the f(x) and x terms. Once you have done that, solve for the new f(x). Finally, what you'll have remaining is the inverse function. The work is done for you below:

f(x) = $\sqrt{2x + 2}$ ----> Switch the x and f(x)

x = $\sqrt{2f(x) + 2}$ ---> square both sides

$x^{2}$ = 2f(x) + 2 ---> subtract 2 from both sides

$x^{2}$ - 2 = 2f(x) ----> divide both sides by 2

$\frac{x^{2} - 2}{2}$ = f(x) ----> switch the order for formatting sake.

f(x) = $\frac{x^{2} - 2}{2}$

A paper company needs to ship paper to a large printing business. The paper will be shipped in small boxes and large boxes. Each

Nataly_w [17]

Answer:

12 small boxes

8 large boxes

Step-by-step explanation:

let x be the number of small boxes shipped

let y be the number of large boxes shipped

This means:

the total number of boxes is 20, so

x + y = 20

the number of 50 pound boxes is x and the number of 100 pound boxes is y and together there are 1400 pounds, so

50x + 100y = 1400

Then, solve

First, simplify the equation 50x + 100y = 1400 by dividing both sides by 50

x + 2y = 28

Now, subtract the two equations:

x + 2y = 28

- (x + y = 20)

y = 8

Now plug this into the equation x + y = 20

x + 8 = 20

x = 12

So the number of small boxes is 12 and the number of large boxes is 8.

Here's a graph:
