The |x| operator means 'absolute value' or the positive value of the negative values. To help this make sense, here's a visual representation:

But,

Do you see what I mean? BTW, your answer will just be 8 + 8 or 16.
Answer:
7/10 can't be simplified, 2/10->1/5
Step-by-step explanation:
7/10 cannot be simplified as 7 and 10 don't have any common factors other than 1
2/10 can be simplified by a factor of 2 to get 1/5
Answer:
1
Anything to the 0th power is 1.
The equation of a straight line is given by:
y = mx + c
where m is the slope and c is the y-intercept.
From the given graph, the y-intercept is 1.
The slope of a straight line is given by:

Where

and

are two points on the line.
From the graph, (0, 1) and (14, 8) are two points on the line, thus:

Therefore, the equation representing the graph is
