If x=8 then y=4. What is the value of x when y=8?

x = 16

Step-by-step explanation:

You can create a proportion to solve this.

X over Y --> 8 over 4 (picture this in fraction form lol)

8 over 4 = x over 8

Cross-multiply

4x = 64

Divide both sides by 4

x = 16

lol we need to see what the question is asking about

step-by-step explanation:

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
