Five times the sum of a number and -1 is the same as 6 times the number. What is thisnumber?

- 5

Step-by-step explanation:

let the number be n then 5 times the sum of n and - 1 is 5(n - 1), thus

5(n - 1) = 6n ← distribute left side

5n - 5 = 6n ( subtract 5n from both sides )

- 5 = n

Thus the number is - 5

-5

Step-by-step explanation:

Let the number be n

5(n+(-1)) = 6n

5n - 5 = 6n

-5 = 6n - 5n

n = -5

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.
