Answer: -7, 12
Step-by-step explanation:
a+b = 5
a*b = -84
a = 5-b
(5-b)*b = -84
-b^2 + 5b + 84 = 0
(-b - 7)(b + 12) = 0
The roots are -7 and 12.

The midpoint of these two points is (-1, 8).
In order to find the midpoint, you must take the average of each part of the coordinates. You do this by adding them together and dividing by 2. We'll start with the x-coordinates.
(-1 + -1)/2 = -1
Now we'll use the y-coordinates.
(10 + 6)/2 = 8
This gives us the ordered pair of (-1, 8)
Answer:
0.5 or 1/2
Step-by-step explanation: Use the slope formula: y2 - y1 / x2 - x1
0 - (-2) / -5 - (-9)
2 / 4
= 0.5 or 1/2
Answer:e=-10
Step-by-step explanation:
-2e-7=13
-2e=20
e=-10
The second table. A linear function is a function where adding the same amount to x should add the same amount to y.
In table 2, you can see that adding 1 to x adds 2 to y. All the other tables describe non-linear functions.
