Factorize the quadratic.

We have
, so

Now, both
and
(since the absolute value of any number cannot be negative), so we just need to worry about when the left side is exactly zero. This happens for

So the solution to the inequality is the set

It’s an irrational number
Hope this helps!

Step-by-step explanation:
<u>Step 1: Define</u>
Point (-4, -1)
Point (1, 4)
<u>Step 2: Find slope </u><em><u>m</u></em>
Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>
- Substitute [SF]:

- Add:

- Divide:

The answer is Y=11, X=-1
Here's my work:
x=-12+y
-6(-12+y)+2y=28
6*12= 72
72 -6y +2y=28 (now we combine like-terms)
72-4y=28 (now divide by -4)
-18+y=-7 (add 18 to both sides)
y=11
next part we find x:
x=-12+(11)
x=-1
