Answer:
Midpoint is 
Step-by-step explanation:
Midpoint = 
= 
= 
= 
Midpoint is (-37/2, 14)
-3 + -3 = 0
-5 + 1 = -4
vector = < 0,-4 >
Answer:
1. 74 because 8(10) - 6
2.4(4) - 5(3) = 1
3. 7(3)+8(4) * 2 = 106
4. A
5.a
6. 20.5
7.26
8.a
9.a
10a
Step-by-step explanation:
Not entirely sure, but it seem the answer could be B.) It will not be spread out vertically across the entire coordinate plane because in step 5, Nancy selected an incorrect scale on the y-axis.
Direct variation is y=kx, inverse variation is y=k/x....
-5y=-2x divide both sides by -5
y=2.5x
So this is a direct variation with a constant of 2.5
