No real roots or no real zeros.

Step-by-step explanation:

The given function is

We need to find the number of real zeroes.

The given function is a quadratic function.

Let a quadratic function is .

If , then the function has no real root.

If , then the function has one real root with multiplicity 2.

If , then the function has two real roots.

In the given function,

So,

The value of discriminant is -63.

Therefore, the given function has no real root or no real zeros.

She payed $25 (not including tax). To work this problem, you need to set up a ratio.
x 35
-- = --
40 100

This will show you how much money is off of the item.

After you solve the ratio (cross multiply and divide), you should have gotten the answer $14. Then you subtract 14 from 40 to get the price of the item currently at 35% off. The answer would be $25.
