Which relation is a function?

Mathematics
1 answer:
Darya [45]3 years ago
3 0

Hello from MrBillDoesMath!

Answer:

Choice B

Discussion:

The answer shown highlighted is the correct answer

For a function,  each value in the domain should be assigned a unique value in the range. In the case of ordered pairs, each x value in an order pair should have a unique  y value.  This aspect fails for Choices A, C, and D.  Details follow.

Choice A: Not a function because  (3,3), and (3,2)  both have x = 3 but associated y value is not unique (equal 3 or 2)

Choice C:  Not a function because (1,-1) and (1, -2)  both have x = 1 but  associated y value is not unique (equals -1 or -2)

Choice D: Not a function because  (2,3) and (2,1) both have x= 2 but associated y value is not unique (equals 3 or 1)

Choice B has no such issues as an x value is repeated.

Thank you,

MrB

What is the numerator of the fraction equivalent to 3\5 that has a denominator of 30
aliya0001 [1]
Well, the numerator is the number on top, so in the fraction 3/5, 3 is the numerator. To find the equation with a denominator of 30 that is equivalent, find what the difference is. 30/5 = 6. So now, multiply the numerator by 6. 6 * 3 = 18. The new fraction is 18/30. The numerator is 18. Hope this helps!

5+3r=5r-19(if there is no solution,type in ''no solution'')r= Answer
TEA [102]

Answer: 12 = r

Step-by-step explanation: When we have this kind of a setup, we want to put our variables together on one side of the equation and our numbers together on the other side of the equation.

First, let's put our variables on the right side by subtracting 3r from both sides of the equation. That gives us 5 = 2r - 19.

Now we can move our numbers to the left by adding 19 to both sides of the equation and we get 24 = 2r.

Divide both sides by 2 and 12 = r

Note:

Don't just do this problem in your head. It's extremely important to develop the habit of putting all your steps down on paper or digitally. It will really pay off for you down the line.
