A pool is filling up at a rate 7 gallons per minute. which equation best represents y, the total amount in the pool after x minu
tes?
A. x=7y
B. y=7x
C. y=7+x
D. x=7+y
2 answers:
B. y = 7x
7x is the steady rate of 7 gallons per minute. The number of minutes can also be plugged into x to find the volume of the pool after x minutes.
B. y=7x
y represents the amount of water in the pool after x minutes, that means it's going to be the result.
x represents minutes.
you are multiplying it because it's per minutes

Answer:
60
Step-by-step explanation:
50+50+50+50+100= 300
divide by 5 students
300/5 = 60
f(x) = a - x
y = a - x
y + x = a - x + x
y + x = a
y + x - y = a - y
x = a - y
f-¹(x) = a - x
Answer:
A) y=-x+8
Step-by-step explanation:
Parallel lines have the same slope. So, next you need to find the y-intercept (b) of the line. (see attached work)
