<span>12x+7 < -11:
Subtract 7 from each side.
12x+7 < -11
-7 -7
12x < -18
Divide each side by 12.
12x < -18
----- -----
12 12
x < -1.5 or x < -3/2
</span><span>5x-8 > 40:
Add 8 to each side.
5x-8 > 40
+8 +8
5x > 48
Divide each side by 5.

Actually Welcome to the Concept of the Functions.
So here to get the (f-g) (x) , we do the subtraction of the two functions now,
==> 8x + 5 - (9x -2)
===> 8x + 5 -9x +2
===> 8x - 9x +7
==> -x + 7
hence the new function (f-g) (x) = 7 - x
and the domain is from (- infinite to + infinite)

Okay so you’re trying to get them to add up to 540 degrees.
On one side of the equation, have this, and on the other, add up your degrees on the shape.
(3x)+(10x-8)+(5x-12)+(120)+(2x)=540
Start by combining like terms on the left side.
20x+100=540
-100 -100
___________
20x=440
—— ——
20 20
x=22
(On this step, I was just solving and isolating the variable.)
Hope this helps!!
Answer:
C. 3
Step-by-step explanation:
Formula for slope is given as 
The coordinates of any two points can be used in this formula. Let's use, (1, 5) and (2, 8).
Let,


Plug the values into the formula:



That will be 40 because the problem is making you multiple
