Is {(9,- 15), (0, 0), (4,0), {9, 2)} a function

no im pretty sure they are not functions

Correct me if im wrong also learning

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

  the correct choice is marked
