Bob works as a tutor for an hour and as a waiter for an hour. this month, he worked a combined total of hours at his two jobs. let be the number of hours bob worked as a tutor this month. write an expression for the combined total dollar amount he earned this month.

1+1=2x30

Step-by-step explanation:

Because it is a expression, you don't have to solve it. You should first turn it into a promblem that you can solve. for example you know that bob workes two hours each day, and there are 30 days in a month. you would do 30 times 2 and get the answer 60, so it would look like this ,2h x 30d=$60. when i comes down to doing an expression it pretty much the same as solving the original problem.

goog be able to you with that maybe

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.
