Answer:
FG = 18
Step-by-step explanation:
FG + GH = FH
FG + 31 = 49
Subtract 31 from each side
FG +31-31 = 49-31
FG = 18
It is empty a gallon every two and a half minutes so 2 1/2x x=gallons of water
it will take 12 1/2 minutes to completely empty since it takes 2 1/2 minutes per gallon.
the tank was full 7 1/2 minutes before Jada arrived. 10-7= 3 so it emptied 3 gallons before Jada arrived. It takes 2 1/2 mins for a gallon to empty so 2 1/2 times 3 equals 7 1/2 mins
Answer:
Graph D.
Step-by-step explanation:
The line goes through the origin, and therefore shows direct variation.
Exponential decay is whenever the rate^2<1. So exponential growth occurs whenever r^2>1.
In this case only y=5(4^x) is exponential growth as 4 is greater than 1
X = 1 , y = - 2
Hope this helped
