Answer:

a= -36

Step-by-step explanation:

1. Subtract 2 from both sides

    2 + a/6 -2 = -4 -2

2. Simplify

    a/6 = -6

3. Multiply both sides by 6

     6a/6 = 6(-6)

4. Simplify

     a = -36

KonstantinChe [14]

Answer:

Step-by-step explanation:

\frac{9a^{2}-5}{b^{2}+2}+\frac{-2a^{2}+4}{b^{2}+2}=\frac{9a^{2}-5-2a^{2}+4}{b^{2}+2}\\\\=\frac{9a^{2}-2a^{2}-5+2}{b^{2}+2}\\\\=\frac{7a^{2}-3}{b^{2}+2}

What is the slope-intercept form of the equation y - 7= -5/2(x+4)
GREYUIT [131]
The first thing I would probably do is distribute (multiply) the -5/2 into the parenthesis:

= (-5/2)x + (-20/2)

Notice how I am not putting the x into the fraction. This is to make it easier to see the slope-intercept form.

Lets simplify the (-20/2) and then add 7 to both sides:

y - 7 = (-5/2)x - 10

y = (-5/2)x - 3

Your answer would then be:

y = (-5/2)x - 3

y = mx + b

Since it is now in the requested format.
