Answer:
Q' ( 0,5)
Step-by-step explanation:
Q(-4, 7)
To shift to the right, add the amount to x
x+4
To shift down, subtract from y
y -2
Q' ( -4+4, 7-2)
Q' ( 0,5)
False. You can find the solution more quickly by solving the system algebraically.
-4x + 2y = 18
Since y=-3x+4,
-4x + 2(-3x+4) = 18
-4x - 6x + 8 = 18
-10x = 10
x = -1
y = -3x+4 = 7
If i'm correct you should add 0.5 mL to your 1 gallon tank, and I would say about 1.25 mL to your 2.5 gallon. It will not be extreme if you end up putting a little more in than you are supposed to. I'm not 100% because i haven't slept so my brain is being slow.
It would be 5 tens + 4 tens = 9 tens
