Answer:

-38

Step-by-step explanation:

So we have the equation:

$-(6m+8)=4(17-m)$

On the left, distribute. On the right, distribute also. So:

$-6m-8=68-4m$

Add 6m to both sides:

$-8=68+2m$

Subtract 68 from both sides:

$-76=2m$

Divide both sides by 2:

$m=-38$

And we're done!

MissTica

Answer:

Domain is all Real Numbers and the Range is all Real Numbers.

Step-by-step explanation:

It is a function.

The graph of this function is a straight line passing through the x axis at (10,0) and the y-axis at (0,10). The line continues to the left and right without bounds.

So the Domain is all Real Numbers and the Range is all Real Numbers.

-6(2r +8)=-10(r-3)<br> I need the work to

barxatty [35]

Answer:

r = -39

Step-by-step explanation:

So we are trying to solve the equation for r.

-6(2r + 8) = -10(r - 3)

Divide both sides by -2. (This will make distributing much easier.)

3(2r + 8) = 5(r - 3)

Distribute the 3 on the left side and the 5 on the right side,

6r + 24 = 5r - 15

Subtract 24 from both sides.

6r = 5r - 39

Subtract 5r from both sides.

r = -39

So now we have solve the equation.

I hope you find my answer and explanation to be helpful. Happy studying. :)
