8 4/8 - 2 2/8 = 6 2/8in or 6.25in
we use equation 1 first.
-2x -y = -9
-y = -9 + 2x
y = 9 -2x
We substitute value of y in equation 2
5x - 2 (9 - 2x) = -9
5x -18 - 4x = -9
5x - 4x = -9 + 18
x = 18 -9
x = 9
We now find the value of y
-2x -y = -9
-2 (9) - y = -9
-18 - y = -9
-y = -9 + 18
y = 9 - 18
y = -9
It might be the first box, because i had that same question on my hw this year, lol what a coincidence
Answer:
1 solution
Step-by-step explanation:
y=16, r=-21/2
Answer:
Step-by-step explanation:
Ummm, y = mx+b is called the slope-intercept form because you can just read them off:
slope = m
y-intercept = b
Now can you pick a choice?
