Step-by-step explanation:
Answer:
x=1, y=8
Step-by-step explanation:
Plug y=8x into y=10x-4.
8x=10x-4
Subtract 10x from each side.
-2x=-2
Divide each side by -2.
x=1
Plug x=1 into y=8x.
y=8(1)
y=8
Answer:
(8,-9)
Step-by-step explanation:
using the principle of vectors, you match each number to their coordinates and add them
so we have (7+1,-12+3)
which is equal to (8,-9)
A = L * W
(9/10) = (3/2) * W
Divide both sides (3/2)
(9/10) / (3/2) = W
(9/10) * (2/3) = W
18/30 = W
6/10 = W
W = 3/5 mile
