Answer: x = -11
Step-By-Step:
We can start by combining like terms on the left side.
-20 - x = 4x - (3x - 2)
Now we need to distribute the negative on the right side.
-20 - x = 4x - 3x + 2
Now combine like terms on the right.
-20 - x = x + 2
Now add 20 to the other side
- x = x + 22
Subtract x from the left side.
-2x = 22
Now divide by -2.
x = -11
The multiplicative inverse of 1 half would be <u>2</u>, or 2 over 1 (2/1).
Hope this helps. :)
Answer:
I'll explain you number one
3
Step-by-step explanation:
You first subtract the single number (1) subtract to 10 which gives you 9, then you will divide 3 from 9 which gives you 3
Sorry I couldn't help you with there other ones.
Answer:
10. 
11A. 
11B. 
Step-by-step explanation:
10. Let's first write the slope-intercept form down and fill in the information we got (which is not much).

Now we just need to find the b; the y intercept.
To do that, we plug in the point given (-2,6).

A parallel line always has the same slope as its pair
11A. 
A perpendicular line has it's slope same as it's pair, <em>but</em> it is multiplied by
and the numerator and denominator are switched around.
11B.
