Is the relation in this set of points a function
natita [175]
It is not a function—an element from the domain is paired with more than one element from the range. Specifically, the input value of 4 corresponds to two output values: 5 and -4.

A function can only take on one output for each input. It only takes one input value to associate with more than one output value to be invalid as a function.

What does 2 3/5 divided by 1 1/25 equal

Alright, so let's make 2 3/5 into an improper fraction.

2 x 5 = 10 + 3 = 13

Now you multiple the numerator and denominator from both fractions. (I'm not going to do the math for you. Hope this helped and sorry if my explanation is...yeah.)

Multiply both sides of the equation by 28 4y+7=10
Then move constants to the right side and change its sign 4y=10-7
Now subtract the numbers 4y=3 divide both sides by 4 so your answer is y=3/4
