The zero product property tells us that if the product of two or more factors is zero, then each one of these factors CAN be zero.
For more context let's look at the first equation in the problem that we can apply this to:

Through zero property we know that the factor

can be equal to zero as well as

. This is because, even if only one of them is zero, the product will immediately be zero.
The zero product property is best applied to
factorable quadratic equations in this case.
Another factorable equation would be

since we can factor out

and end up with

. Now we'll end up with two factors,

and

, which we can apply the zero product property to.
The rest of the options are not factorable thus the zero product property won't apply to them.
Answer:
The unit rate is 2 cups of flour per cup of sugar.
Step-by-step explanation:
Answer:
The multiplicative rate of change of the function is 
Step-by-step explanation:
You are given the table

An exponential function can be written as

where b is the multiplicative rate of change of the function.
Find a and b. Substitute first two corresponding values of x and y into the function expression:

Divide the second equality by the first equality:

Substitute it into the first equality:

So, the function expression is

Check whether remaining two values of x and y suit this expression:

So, the multiplicative rate of change of the function is
