The price for digital downloads of music is represented by the linear function f(x) shown on the graph. the price for digital downloads of movies is represented by g(x) = 3x, where x is the number of movies downloaded and g(x) is the total cost in dollars. graph of a line with equation f of x equals one half times x plus 2. the x axis is labeled number of songs, and the y axis is labeled price in dollars. you want to make 2 downloads, and you have $6. determine the least expensive option. you download 2 songs. you download 2 movies. you download 1 song and 1 movie. you don't have enough money for 2 downloads.

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:

d. all of the above

step-by-step explanation:

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement
