Answer:Frederick county:2.5x+15,Montgomery county:3x+10
Step-by-step explanation:
Complete question is;
It took Priya 5 minutes to fill a cooler with 8 gallons of water from a faucet that was flowing at a steady rate. Let w be the number of gallons of water in the cooler after t minutes. Which of the following equations represent the relationship between w and t? Select all that apply
A) w = 1.6t
B) w = 0.625t
C) t = 1.6w
D) t = 0.625w
Answer:
Option A: w = 1.6t
& Option D: t = 0.625w
Step-by-step explanation:
We are told It took Priya 5 minutes to fill a cooler with 8 gallons of water at a steady rate.
Thus;
Rate of filling = 8 gallons/5 minutes = 1.6 gallons/minutes
Now, we are told that w is the number of gallons of water in the cooler after t minutes.
Thus, to find w, we will multiply the rate by t minutes.
w = 1.6 gallons/minutes × t minutes
w = 1.6t gallons
Or we can write as;
w/1.6 = t gallons
0.625w = t gallons
Therefore, options A & D are correct.
y=4^x −1
x intercept is the point when y = 0, so you sub in 0 for y:
0 = 4^x - 1
4^x = 1
Any number excluding 0 that is raised to the the exponent 0 always equals 1, 0^0 is undetermined.
x = 0
x intercept = (0,0)
If the x intercept is at the origin (0,0) than the y intercept is also (0,0)
s is the only line that passes through (0,0)
