Assuming that the pool was drained at a constant rate, the speed at which it was drained can be expressed as a function of time. In this case, the pool level will be expressed in feet per hour.
The time changed by 4 hours (6-2), and the level of the pool changed by -8 feet (2-10). Diving the feet by the hours to get the rate of decreasing depth, we find that the rate equals -2 feet/hour.

Answer:
x,y =2,1
Step-by-step explanation:
3x+4y=10 ................equ1
x-y=1 ................equ2
This system of equations forms a quadratic equation.
Lets use the substitution method in solving this set of equations
from equ 2; x=y+1
substitute x=y+1 into equ 1
3(y+1) +4y=10
3y+3+4y=10
7y=10-3
7y=7
y=7/7
y=1
but x=y+1
substitute the value of y into this equation to get x
x= 1+1
x=2
x,y=2,1
The correct response is X=25
Hi, thank you for posting your question here in Brainly.
Celsius and Fahrenheit are units of temperature, and they can be converted using a formula.
F = C*1.8 + 32
For example, 30°C is
F= 30*1.8 + 32
F = 86°F
Or an easier way to remember without memorizing the formula is by remembering the normal boiling point of water which is 100°C = 212°F.
