Bess and gina earn $45 per week for delivering flowers. bess worked for x weeks and earned an additional total bonus of $20. gina worked for y weeks. which expression shows the total money, in dollars, that bess and gina earned for delivering flowers?

First option:

Step-by-step explanation:

The missing options are:

 We know that "x" represents the number of weeks Bess worked and "y" the number of weeks Gina worked.

According to the data  given in the exercise, Gina and Bess earn $45 per week for delivering flowers, this is:

Since earned an additional total bonus of $20, then the total money in  in dollars that Bess and Gina earned for delivering flowers can be shown with the following expression:

Notice that this expression matches with the one shown in the first option.

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.
