5) twelve divided by a number.
6) x +10
7) 3x-5
8) 6x + 2

5)12/x

6) a number increased by 10

7) three times a number decreased by 5

8) 6 times a number increased by 2

Step-by-step explanation: "a number" refers to a variable.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.

step-by-step explanation:

it would be a on edgenuit y
