Find an equation in slope-intercept form for the line with a zero slope and passes through (12, -9).

Virty [35]

If the slope is 0, then x does not change at all.

take the given y coordinate, and make that the equation.

so y=-9, since the line will never change.

What is the solution to the equation -3d/a^2-2d-8 + 3/d-4 = -2/ d+2

Alex73 [517]

Answer:

d=1

Step-by-step explanation:

$\frac{-3d}{d^2-2d-8} +\frac{3}{d-4} =\frac{-2}{d+2}$

Lets factor the denominator d^2 -2d-8

d^2 - 2d - 8 = (d-4)(d+2)

$\frac{-3d}{(d-4)(d+2)} +\frac{3}{d-4} =\frac{-2}{d+2}$

Now make the denominators same

LCD: (d-4)(d+2)

$\frac{-3d}{(d-4)(d+2)} +\frac{3(d+2)}{(d-4)(d+2)} =\frac{-2(d-4)}{(d+2)(d-4)}$

Denominators are same on both sides

So equate the numerators

-3d +3(d+2) = -2(d-4)

-3d +3d +6 = -2d +8

6 = -2d + 8

subtract 8 on both sides

-2 = -2d

So d=1

Prove that 3:8 is equivalent to 12:32.

ANEK [815]

3:8 can also be written as 3/8

<span>12:32 can also be written as 12/32

</span> $\frac{12}{32} = \frac{3\times 4}{8\times 4} = \frac{3}{8}$

<span>So thus 3:8 is equivalent to 12:32</span>
