On saturdays, when tom gets to work, he a asked to clean a 175-gallon reef tank. his first job is to drain the tank. he measures the amount of water that is draining out and finds that 12.5 gallons drain out in 30 minutes. what is the average rate of change that the water drains in 1 hour? write an equation representing the water draining. how long will it take for the tank to be empty? (hint: use the equation format y= mx + b
m=rate=slope
b=y intercept

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
