Answer:
Step-by-step explanation:
Given equation:
In the given equation, is a coefficient and y is the variable.
coefficient is a constant number or quantity multiplied to a variable in an algebric expression. Like in the above equation is a coefficient and y is the variable. We use term variable for y as its value may vary or change. If variable does not have any coefficient in any expression then in that case, we consider 1 as coefficient, for example: , here variable have 1 as coefficient.
Hence, the fractional coefficient is .
Usually t is used for time. Plug in the correct value for t. Which is 5 hours.
w = -500(5) + 7000 ; Start
w = -2500 + 7000 ; Multiple -500 by 5
w = 4500 ; Subtract 2500 from 7000
So, after 5 hours of draining the pool, 4500 liters (I choose liters. It didn't specify in the question) of water are still in the pool.
A (-9.5, -9.5) B (5.5,-2.5) C (3.5,3.5)
