Answer:
It's B, I'm only trying my best since there is no picture.
Step-by-step explanation:
Step-by-step explanation:
x + y = 9. => 2x + 2y = 18.
2x + 2y = 18
- (2x - 3y = -12)
=> 5y = 30, y = 6.
Therefore x + (6) = 9, x = 3.
The solution is x = 3 and y = 6.
18 would have to be the mean because of the average
x y
1 16
2 12
3 8
5 0
Step-by-step explanation:
you have to substitute ever number on the X side in the equation to get the Y
for example 1 is under x so you will take
y=20-4(1)
y=20-4
y=16
Answer:
The answer to both photos is 1.
Step-by-step explanation:
Rise over run is looking at each plotted point on the graph and counting upward until level with the first point from zero, then going across the graph until you reach the plotted point.
The rise for the first picture is 3/1, and if you reverse them, you get, (1, 3).
- Hope this helps, good luck.
