Harold has been hired as a salesman. he is paid a flat rate of $375 each week and earns an additional $14.25 commission for each sale. if x represents the number of sales and y represents the total earned, which equation will harold determine the amount he earns in one week? (2 points) select one: a. y = $375h - $14.25 b. y = $375h + $14.25 c. y = $14.25h + $375 d. y = $14.25h - $375

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:

the answer is d
