Mathematics
1 answer:
wlad13 [49]3 years ago
8 0

Answer:

\frac{1}{5}

Step-by-step explanation:

\frac{9}{20} - \frac{1}{4}

Make sure they have a common denominator. To do so, you must find a number the both have in come. Here, the number they have in common is 20.

What times 4 equals 20? 5. Whatever you do to the denominator you must do to the numerator.

\frac{5}{5} × \frac{1}{4} = \frac{5}{20}

Now you have \frac{9}{20} - \frac{5}{20} = \frac{4}{20}

Then you can simplify \frac{4}{20} to \frac{1}{5} by dividing it by \frac{4}{4}

Given the graph below, which of the following statements is true?
nirvana33 [79]

Answer:

D) The graph does not represent a one-to-one function because the y-values between 0 to 2 are paired with multiple x-values.

Step-by-step explanation:

Let's find the ordered pairs.

(-4, 4), (-3, 2), (-2, 0), (-1, 0.5), (0, 1), (1, 1.5), (2, 2), (3, 0)

The graph passed through above points.

In the x-coordinates -3, 2 gives the same output. Therefore, the given function is not one-to-one.

Therefore, the answer D)

The graph does not represent a one-to-one function because the y-values between 0 to 2 are paired with multiple x-values.

Hope you will understand the concept.

Thank you.
