What number must be subtracted from -5 for the difference to be -2. explain your answer.

-3

Step-by-step explanation:

Let n be a number

Rewrite the sentence into something that can be interpreted better:

A number subtracted from -5 is -2

Now you can translate the statement into an equation:

-5 - n = -2

Solve for n

-n = 3

n = -3

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.
