Write in point-slope form.

Formula:(y-y1)=m(x-x1)
(y-(-10))=4(x-3)
y+10=3x-12, distributive property

Solve for y

WILL GIVE BRAINLY!!!!!!!!<br> Factor completely 2x2 + 2x − 12.

kipiarov [429]

Step-by-step explanation:

All of these terms have a common factor of 2, and when we take that out we get 2(x² + x - 6). To factor the polynomial in the parentheses, we have to find 2 numbers with a product of -6 and a sum of 1, and these are 3 and -2. Therefore, the final answer is 2(x + 3)(x - 2).

Hope this helps!

2x+7=12x-6 looking for x

Rzqust [24]

Hey!

Let's start by writing the problem:
$2x+7=12x-6$
Subtract 7 from both sides.
$2x+7-7=12x-6-7$
$2x=12x-13$
Subtact 12x from both sides.
$2x-12x=12x-13-12x$
$-10x=-13$
Divide both sides by -10.
$\frac{-10x}{-10}=\frac{-13}{-10}$
$x=\frac{13}{10}$

Let me know if you have any questions regarding this problem!
Thanks!
