Set the denominator equal to 0 and solve for x.

x^2 - x - 6 = 0

Factor.

(x - 3)(x + 2 ) = 0

Set each factor to 0 and solve for x.

x - 3 = 0

x = 3

x + 2 = 0

x = -2

The domain is ALL REAL NUMBERS except that x CANNOT equal 3 or -2.

Please helppp i need this done and i dont know what to do

ioda

Answer:

FRACTION DECIMAL

1/5( 1*2/5*2=2/10) 0.2

3/10 0.3

1/2(1*5/2*5=5/10) 0.5

7/10 0.7

3/4(3*25/4*25=75/100) 0.75

<u><em>NOTE</em></u>: To conert a fraction into decimal, it is required that the denominator be changed into 10, 100, 1000 and so on..... By changing the denominator, we have to first select the appropriate number by which you will be able to convert it into 10, 100 or 1000, and you are also required to multiply that number with the denominator as well as numerator. In the first question, 1/5 we can convert the denoinator into 10, 100 or 1000 as the denominator is 5, whatever you choose, the answer will be correct, so, 1*2/5*2 gives 2/10. Since 10 has one zero, the decimal point moves one time towards the left, which gives 0.2. And you can do the rest according to this way, considering the number of zeroes.

What would y be if 8x-6y=36

kondor19780726 [428]

Answer:

$\quad y=-\frac{2\left(-2x+9\right)}{3}$

Step-by-step explanation:

1. Subtract 8x from both sides:

8x-6y-8x=36-8x

2. Simplify:

-6y=36-8x

3. Divide both sides by -6

$\frac{-6y}{-6}=\frac{36}{-6}-\frac{8x}{-6}$

4. Simplify to get answer
