How to solve 6 1/2 - (-1 7/8) each and every step

67/8

Step-by-step explanation:

6 1/2=13/2

-1 7/8=-15/8

13/2-(-15/8)

13/2+15/8

52/8+15/8

67/8

5x+10 is the correct one

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.
