What is the answer to 8x-9=12+11x

mrs_skeptik [129]

Answer:

x = -7

Step-by-step explanation:

8x - 9 = 12 + 11x

Subtract 11x to both sides of the equation. Then, it will look like this:

-3x - 9 = 12

Add 9 to both sides of the equation. After that, it will look like this:

-3x = 21

Divide both sides of the eqution by -3. Your answer is:

x = -7

What is the slope of 6x + 3y =15?

frozen [14]

Answer:

<h2>The answer is - 2</h2>

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the slope we must first write the equation in the general equation above

That's

6x + 3y = 15

<u>Make y the subject</u>

Send 6x to the other side of the equation

3y = - 6x + 15

<u>Divide both sides by 3</u>

$\frac{3y}{3} = - \frac{6}{3} x + \frac{15}{3}$

We have

y = - 2x + 5

Comparing with the general equation above

Slope / m = - 2

Hope this helps you
