Answer:
y = 5
Step-by-step explanation:
Hello there!
Y is our unknown quantity. We need to find for y.
To do this we will isolate the variable so it equals a number that makes the statement for x true.
To solve this, we will use the division property of equality since this is a multiplication equation. y has to be less than 40.
So we will divide 8/8 to isolate y on one side and then do 40/8 (herby the division property of equality)
Then our answer should be y = 5
To double- check this we could simply substitute 5 for y in the equation; 5 • 8 = 40
Therefore this statement holds to be true
Hope this helps you! :)
A is the only function.
If they list out the x’s (like in B and C) and they have two of the same x’s, it is not a function. If they have those circles (like in D) and one x goes to multiple y’s, then it is also not a function. Hope this helps!
