Answer:
One way to help remember is to visualize it on a number line.
<em>-2</em> is<em> 2 less then 0.</em>
<em>4 </em>is <em>4 more then 0</em>
So, in the equation 
, you start at <em>4</em> then go <u>left</u> on a number line <u>twice</u>.
The same goes for 
, start at <em>-2 </em>on a number line and go <u>right</u> 4 times.
Simply, with negative numbers you go left and with positive you go right.
When you see ![[number]+(-[number])](https://tex.z-dn.net/?f=%5Bnumber%5D%2B%28-%5Bnumber%5D%29)
, all that means is a positive number plus a negative number, which means a positive number minus the number that is negative as a positive. If that sounds confusing it's alright.

This is a reflection along the y-axis. There is no work needed.
Answer:
29° + (x - 5)° = 180°
29 + x - 5 = 180
29 - 5 + x = 180
24 + x = 180
24 - 24 + x = 180 - 24
x = 156
Step-by-step explanation:
A straight line is 180°.
Set all angles (29° and (x - 5)°) equal to 180°.
Then solve for x.
The system is inconsistent because the slopes are the same and the lines are different.
A linear equation is of the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept.
Given the following system of equations:
y = 6x + 2 (1)
y = 6x + 1 (2)
We can see that both equations have the same slope of 6 but have different y intercepts.
Hence the system is inconsistent because the slopes are the same and the lines are different.
