What's 17= z- (-9) days

Mathematics

Z - (-9) is the same as z + 9. Subtracting a negative is the same as adding.

Therefore 
17 = z - (-9)
is the same as
17 = z + 9

To get 'z' all by itself, we need to subtract 9 from both sides. We subtract 9 from both sides to undo the "plus 9" occurring to the 'z' on the right side.

17 = z + 9
17-9 = z + 9=9 ... subtracting 9 from both sides
8 = z
z = 8

So the answer is z = 8

---------------------------

Check:

17 = z - (-9)
17 = 8 - (-9) ... replace z with 8
17 = 8 + 9
17 = 17
Answer checks out

What is the slope of this line?
Katyanochek1 [597]
Hello!

To find slope, calculate the change in y-values and divide it by the change in x-values:

y1 - y2 / x1 - x2

You have the coordinates (-4, 5), (0, 6), and (8, 8). You can use any combination of two of these points to calculate slope. I'll use (0, 6) and (8, 8).

6 - 8 / 0 - 8
-2 / -8
1/4

Answer:
The slope of the line is 1/4
