Pat earns $30.00 for traveling to the homes plus $10.50 for each hour of tutoring. Write a linear equation that models their total earnings for traveling and tutoring for a given number of hours.

30 + 10.50h

Step-by-step explanation:

From the question, we are informed that Pat earns $30.00 for traveling to the homes plus $10.50 for each hour of tutoring.

The linear equation that models their total earnings for traveling and tutoring for a given number of hours would be written as:

= $30 + $10.50h

where h represents the number of hours for tutoring used.

For example, if 2 hours if tutoring was used, the total amount earned would be:

= 30 + 10.50h

= 30 + 10.50(2)

= 30 + 21

= $51

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14
