Answer:

Yes, every input would have exactly one output.

Step-by-step explanation:

You don't even have to solve it, you can look at the x-values and see if there is two of the same number. If there were two of the same number that would mean it is not linear.

Hope that helps and have a great day!

I need help with these my teacher didn’t teach us this
kolezko [41]

Answer:

Step-by-step explanation:

I am very sorry if this doesnt make sense but i tried to give you an example for the first one so you could figure out the 4 and 5.

If y=12 when x=6, determine y when x=18.

Ok if y=12 and x=6 they add up to 18. So X=6 then you are going to have to times 6 by three to get x to equal 18. That means we have to times y by 3 also which equals 36. We can check this by making sure they are congruent or the same. So if the origanal question said y equals 12 and x equals 6. How do you make sure it's the right answer? What do they have in commmon? Well to get 12 you have to multiply 6 by 2 to get 12. And to get 6 you have to divide 12 by 2. So the common number is 2. So for x to equal 18 we have to figure out is the have something in common, so 18 times 3 equals 36 and if 36 divided by 3  we get 18. So the common number is 3.

Factor the common factor out of <br> -12+15X
matrenka [14]
The factors of -12 are: +-(1, 2, 3, 4, 6, and 12).
The factors of 15x are: +(1, 3, 5, 15, and x).
Since the only factors that the two numbers share are 3 and 1, those are your common factors with 3 as your GCF.
