Answer:
There are no roots
Step-by-step explanation:
The Roots are:- x-values for which the function equals zero
and this function doesn't intersect with x-axis (There are no X-values that we can plot into this function and get zero as output)
which mean there are no root for this function
48.00 is the answer your looking for
There is a formula:
(Pump1 Time * Pump2 Time) / (Pump1 Time + Pump2 Time) = Total Time
Let's say Pump 1 is the old pump
(15 * Pump2 Time) / (15 + Pump2 Time) = 5 Hours
Solving for Pump 2 time
Pump 2 time = (Pump 1 time * Total Time) / (Pump 1 time - Total Time)
Pump 2 time = (15 * 5) / (15 - 5)
Pump2 time = 75 / 10
Pump2 time = 7.5 Hours
and Happy New Year!!!!!
Double Check
(15 * 7.5) / (15 + 7.5) = Total Time
112.5 / 22.5 = 5 Hours Total
Answer:
c y=6x+4
Step-by-step explanation:
y=mx+b. m= slope b= y intercept
at x=0, the graph is at y=4, so that is b. Slope is up/over. so from point (0,4) to point (2,16), the graph went up 12 and over 2. 12/2=6
