Answer:
b) Take the current height, and add up 15.
c) y = 80x + 15
where y is the height of the water in the pool, in centimeters
where x is the time since the hose is in the pool, in hours
d) 180 = 80x + 15
165 = 80x
x = 165/80 = 2.0625 hours, which is also 2 hours and 3 minutes.
This is not a function but the domain is x and the range is going to y so the first is the domain and the second box it the range

Answer:
x = 
Step-by-step explanation:
Let the number be x
x + 2x² = 10
Factorize x + 2x²
x(1 + 2x) = 10
Divide both sides by (1 + 2x)
x =
