12 + 2x - x = 9x + 6 <br><br><br> I need help!!
stich3 [128]

Answer:

3/4

Step-by-step explanation:

Start by simplifying (2x-x) to just (x)

The equation should now look like this: 12+x=9x-6

Now subtract the x on the left side of the equation on both sides.

The equation should now look like this: 12=8x-6

Now add 6 on both sides

The equation should now look like this: 6=8x

To get x by itself you must divide 8 on both sides

The equation should now look like this 6/8=x

Don't forget to simplify your fractions!

6/8 simplified is 3/4, giving you the answer 3/4

What is the slope of all lines parallel to the line 4x-5y+-1?
Bond [772]

Given equation of the line ,

\implies 4x - 5y +(-1) = 0

Simplify ,

\implies 4x - 5y - 1 = 0

Transpose terms to RHS ,

\implies 5y = 4x - 1

Divide both sides by 5 ,

\implies \boxed{ y =\dfrac{4}{5}x -\dfrac{1}{5}}

Now we know the slope intercept form of the line as y = mx + c we have ,

  • m =\dfrac{4}{5}

As we know that the slope of all parallel lines are same . Henceforth ,

  • m_{|| \ lines } =\dfrac{4}{5}
