Simplify. x-2/(x^2+4x-12)
Serhud [2]
In order to solve this you need to factor the denominator. 
x^2 +4x - 12
I see that 12 is a product of 6 and 2 and 4 and 3 and 1 and 12.
I pick the two products that, when added together, give me the 4x term.
Here it's 6 and two I just need to make one of them a negative.
now put them in this form:
(x + 6)(x-2) 
In the fraction I see that there is an x-2 in the numerator. This can cancel out with the x-2 in the denominator. Now you have 1/x-6 but remember you can never have a zero in the denominator so x can't equal -6. 
And you're done!

Write an equation for the number of points, y Enrique scores on the test when he answers x questions correctly.
kramer
<span><u><em>Answer:</em></u>
1. 3x = y
2. 7x= y.
<span>
<u><em>Explanation:</em></u>
If x is the amount of points each question that is answered correctly received then the coefficient that x is multiplied by will be the amount for each test.

For the first equation we have 3 as the amount answered correctly time x the points each one is worth = total points y.

For the second equation we have 7 as the amount answered correctly time x the points each one is worth = total points y .

Solve for x and graph the solution on the number line<br> 15 &gt; 2x – 9 &gt; -23
Monica [59]

The answer is 12>x>-7

Step-by-step explanation:

it's first divided into 2 parts

1 . 15 > 2x - 9

2. 2x - 9 > -23

Then solve them individually.

let's do it,

<u>First half</u>

15 > 2x - 9

15+9 > 2x

24 > 2x

24/2 > x

12>x

<u>Second half</u>

2x-9>-23

2x>-23+9

2x>-14

x>-14/2

x>-7

<u>Joining of the two halves</u>

We have :

12>x>-7

You are trying to recreate flubber because you are obsessed with that movie and you thought it was the coolest. you take 70% sli
german

Let x be the amount (gal) of the 40% slime solution you end up using. You want to end up with 120 gal of the 50% solution, so that you would use 120-x gal of the 70% solution.

You want the final solution to consist of 50% slime, or 60 gal of slime. Each gal of the 40% solution contributes 0.4 gal of slime, while each gal of the 70% solution contributes 0.7 gal of slime. This means

0.4x+0.7(120-x)=0.5\cdot120=60

\implies0.4x+84-0.7x=60

\implies24=0.3x

\implies x=80

so the answer is B.
