An undefined slope is NOT the same as y= 0, since it is a vertical line. The x-coordinate never changes even if the y-coordinate is different. There is no run.
Answer:
-7/2
Step-by-step explanation:
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
Answer:
f(x) = (x+5)(x-1)(x-3)
Step-by-step explanation:
From the graph, we have that the function intercepts the x-axis at the points x = -5, 1,3
From here, we have
x = -5
x = 1
x = 3
So we have the factors as;
x + 5, x - 1 , x - 3
So what this mean is that we have the function as;
f(x) = (x+5)(x-1)(x-3)
