Answer:

Step-by-step explanation:
The given function is

To find k(-5), we put x=-5 into the given function to get;

Multiply out to obtain;

This is the same as;

This simplifies to

Cost of a ticket = $19
So, cost of two tickets = 19 * 2 = $38
Now, he makes, $4.75 in an hour.
Let, the number of hours for that much money = x
It would be: 4.75x = 38
x = 38 / 4.75
x = 8 hours
In short, Your Answer would be 8 hours
Hope this helps!

Let's calculate for the tablespoons of sugar to tablespoons of milk ratio for Mark, Sharri and Eve.
Mark: 3/2 = 1.5
Sharri: 4/3 = 1.3
Eve: 9/6 = 1.5
From the solution, Eve has an equivalent ratio to that of Mark's.
C) They solve the same number of problems per minute
172.5 Divided by 2
115 divided by 2
= 57.5
