Answer:
For
minutes Elena add water to correct the error.
Step-by-step explanation:
The capacity of the washing machine is
gallons.
She uses
gram soap for
gallon of water
Her son by mistake dissolved
grams of soap to
gallons of water.
gram soap is right for
gallons of water, thus
gallon of water must be added more.
She pore water
gallons per minute thus,
gallons of water will take
minutes.

Multiply both sides by x so that x will be in the numerator
The domain is all the x values (range is y values). Remember to put the x values in numerical order.
So: Domain = {-5, -5, -2, 3}.

<h3>How to determine the
exponential equation?</h3>
An exponential equation is represented as;
y = ab^x
Where
a = y, when x = 0
From the table, we have:
y = 1796 when x = 0
So, we have:
y = 1796b^x
Also, we have the point (1, 2097)
This gives
2097 = 1796b^1
Divide by 1796
b = 1.17
Substitute b = 1.17 in y = 1796b^x
y = 1796(1.17)^x
This means that the exponential equation is y = 1796(1.17)^x
After 15 hours, we have:
y = 1796(1.17)^15
Evaluate
y = 18928
Hence, the number of bacteria present after 15 hours is 18928
