Answer:
C = 12 + 15(x - 4)
C = 15x - 48
Step-by-step explanation:
Let the number of hours = t
The total amount Miguel earns =
C
To edit a manuscript, Miguel charges 12 dollars per hour for the first 4 hours and 15 dollars per hour after the first 4 hours.
C = 12 + 15(x - 4)
Expand the t
C = 12 + 15x - 60
C = 15x - 48
Therefore, an expression for the amount, in dollars, Miguel charges if it takes him t hours to edit a manuscript, where t>4 is given as:
C = 15x - 48

Answer:
He omitted the value "6" from the input value and added it to the output values. Also, he omitted the value "12" as an output value.
Step-by-step explanation:
Bobby didn't map the relation well. He omitted "6" which is supposed to be an input value and rather included it among the output values (y-values).
"12" was omitted also under output values.
All of these make the the relation not to be a function anymore.
If Bobby had mapped the relation well, the ordered pair would have obviously been a function as every x-value will have exactly one y-value assigned the it.
