Answer 1

Answer:

It would be relation B and f (x)

Step-by-step explanation:

for it to be a function X (-8) can only have one outcome, however that isn't the case with A.

and I believe if I'm remembering correctly, one-to-one correspondence is each element of one set is only paired with one element of the other set which isn't true for B, so it should be f (x), though you may want to look it up for yourself to make sure.

1. 42+14x
2. 3(2x + 9)

Answers

Answer:

1. 56x 35x

what you had to do was add 42 plus 14x which gives you 56x. then for number two you had to multiply the numbers inside of the parenthesis by the number outside of the parenthesis which will give you 35x.

I’m not sure but, I think the second one is 6x+27. I don’t think you can’t simplify the first one, if that’s what your asking. But, if your asking what x is, please tell me and I’ll do that instead.

Step-by-step explanation:

Answer: y=7.5+-5

Step-by-step explanation:

Divide 3y from itself and -15 to cancel out the Y variable. So Y is equal to -5. Then you would be left with -2x=-15. So then you would have to divide -2x from itself and -15, which would give you 7.5, and that is your x variable.

Answer:

the ans is 5

Step-by-step explanation:

2j+5=3+2j+2 cancel equal terms which is 2j

so what we have left is

5=3+2

5=5

so 5 is the ans

Answer: infinity many solutions

Step-by-step explanation:

2j + 5 = 3 + 2j + 2

Combine numbers in the right side

2j + 5 = 2j + 5

Minus the smallest j from both side in this case u get rid of both j’s which mean -2j

5 = 5

Divide by 1 or -5

Which mean we get 5 = 5 or 0 = 0
