Michael works as a tutor for $9 an hour and as a waiter for $8 an hour. this month, he worked a combined total of 105 hours at his two jobs.

let t be the number of hours michael worked as a tutor this month. write an expression for the combined total dollar amount he earned this month.

Hence, an expression for the combined total dollar amount he earned this month is  

Step-by-step explanation:

Since we have given that

Cost per hour Michael works as a tutor  = $9

Cost per hour Michael works as a waiter = $8

Number of hours he worked combined = 105

Let the number of hours Michael worked as a tutor be 't'.

Let the number of hours Michael worked as a waiter be '105-t'.

According to question, we get that

Hence, an expression for the combined total dollar amount he earned this month is  

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
