If f[x]=16x-30 and g[x]=14x-6 for which value of x does [f-g][x]=0

[f-g][x] will equal zero when x = 12

Step-by-step explanation:

First find  [f-g][x]:

f(x) - g(x) = 16x - 30 - (14x - 6)

               = 2x - 24

Now set this equal to zero and solve the resulting equation for x:

2x - 24 =  0

This yields x = 12;  [f-g][x] will equal zero when x = 12

answer: 819.89 miles across america

step-by-step explanation:

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.
