120, 90, 30 if you're going from the depths of the water to water level
Answer:

Step-by-step explanation:
how can you solve y = -2x + 25 by subtraction
In case you're not already aware, the expression
is called the "difference quotient" and represents the average rate of change of a function
over an interval
.
For the function
, by substituting
we get

Then the difference quotient is


where the last equality holds as long as
.
It was used to see how your basic math skills
I would probably distribute 15 with the parentheses 15x 9860 which is 147,900 then you would add 6997+147,900
Y= 154187
