Answer:
I think it would be 55+8x. I hope this helps. :)
Step-by-step explanation:
55 gallons of water
8 gallons per minute
It would be 55 gallons (the original amount in the tank) plus 8 gallons per minute. (8x)
x = how many minutes the tank is being filled up more.
so if you were to fill up the tank another 5 minutes, the equation would be 55+8(5)
55+40
95 would be the answer.
The coordinates of C are (3, 2)
The coordinates of D are (4, 1)
Answer:
B
Step-by-step explanation:
Both of them have the same variable and are both raised to the 5th power (Like the example in the last sentence of the text)
C is the right answer because the period should be pi/(1/3), so the answer is 3pi
