Answer:
3y
Step-by-step explanation:
Answer:
x = -18, y = 14
Step-by-step explanation:
4x + 6y = 12
x + 2y = 10
Divide both sides of the first equation by 2. Write the second equation below it.
2x + 3y = 6
x + 2y = 10
Rewrite the first equation. Multiply both sides of the second equation by -2 and write below it. Then add the equations eliminating x.
2x + 3y = 6
(+) -2x - 4y = -20
-------------------------
-y = -14
y = 14
Substitute 14 for y in the second equation and solve for x.
x + 2y = 10
x + 2(14) = 10
x + 28 = 10
x = -18
Solution: x = -18, y = 14
Answer:
32400 inches per hour.
Step-by-step explanation:
9 x 60 (how many seconds are in a minute) = 540
540 x 60 (how many minutes are in a hour) = 32400.
Step-by-step explanation:
p = -1, -4
q = -2, 2
p-q = (-1, -4) -1(-2, 2)
= 1, -6
