Answer:

\frac{1}{6} a-\frac{1}{6}

Step-by-step explanation:

-\frac{2}{3} a+\frac{5}{6}a-\frac{1}{6}

=-\frac{4}{6} a+\frac{5}{6}a -\frac{1}{6}

= \frac{1}{6} a-\frac{1}{6}

Answer:

\frac{( - 2)}{3} a +  \frac{5}{6}a -  \frac{1}{6}  \\   = \frac{(- 4a) + 5a - 1}{6} =    \frac{(a - 1)}{6}

hope this helps.

Write an equation of the line in slope-intercept form.<br><br><br><br> The equation is y= <br> .
aivan3 [116]

Answer:

y = x + 2

Step-by-step explanation:

     Slope-intercept form is y = mx + b where m is the slope and b is the y-intercept. Here, b is equal to 2 because the line crosses the y-axis at 2. THe slope is rise over run, or the change in y divided by the change in x. From the two points given, we get 3/3 which is equal to 1. 1x equals x, so this gives us "no slope." Putting it together gives us y = x + 2.

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

Which of the following is the solution to 6/(x+2) = 5/4x?
Oliga [24]

Answer:

The answer to your question is     x = 10/19

Step-by-step explanation:

Equation

                      6 / (x + 2) = 5 / 4x

To solve this equation use cross multiplication

                      6(4x) = 5(x + 2)

Simplify

                     24x = 5x + 10

Subtract 5x in both sides of the equation

                     24x - 5x = 5x - 5x + 10

Simplify

                     19x = 10

Divide by 19 both sides

                     19x/19 = 10/19

Simplify

                         x = 10/19
