3 + j
____ = 2
11

j =?

Answers

In this question you need to isolate j. First you multiply 11 on both sides to make 3 + j not a fraction anymore.

3 + j = 22.
Then you isolate j by subtracting 3 on both sides since you must cancel the 3's out to isolate j. Then you get an answer of j = 19

To become a member of an ice skating rink, you have to pay a $30 membership fee.The cost of admission to the rink is $5 for members, and $7 dollars for nonmembers. After how many visits to the rink is the total cost for members, including for membership fee, the same total cost for nonmembers?

Answers

30 = 5(m) + 7(n)

5(a) + 30 = 7(a)

(a) is the number of visits!

15 = (a)

5(15) = 75 + 30 = 7(15) = $105

If the x value is reapeted in a set of x values, is it a function?when finding a function do you loko at x values or y values?

Answers

❅☃ If the x value is repeated it is considered a non-function.
So if we had x values of:
2
3
6
it is a function
but if we had
3
6
6
it is a non function because the 6 was repeated
❅☃ Yes, you have to look at the x values, if you do not look at the x values, then you cant determine the functions.

yes it is still a function it just wont be linear
