3. Rewrite -2x + 3y = 6 in slope intercept form.

zaharov [31]

The equation in slope-intercept form is:

$y=\frac{2}{3}x+2$

Further explanation:

The standard slope-intercept form is:

$y=mx+b$

Given equation is:

$-2x+3y=6$

In order to bring the equation in slope-intercept form we have to isolate y on left hand side of equation

So,

Adding 2x on both sides

$-2x+3y+2x=6+2x\\3y=2x+6$

Dividing both sides by 3

$\frac{3y}{3}=\frac{2x+6}{3}\\y=\frac{2x+6}{3}$

Simplifying

$y=\frac{2x+6}{3}\\y = \frac{2x}{3}+\frac{6}{3}\\y=\frac{2}{3}x+2$

The equation in slope-intercept form is:

$y=\frac{2}{3}x+2$

What are soulutions to x^2 - 2x - 24 = 0 who is brainliest

ratelena [41]

Answer:

(x - 6)(x + 4) = 0.

Step-by-step explanation:

With your case of x2 - 2x - 24, we have b1+b2 = -2 and b1b2 = 1*(-24) = -24. So the equation x2 - 2x - 24 = 0 becomes (x - 6)(x + 4) = 0.
