To get the result we can use knowledge that reading is 2 times longer than HW.
To find this value we just have to multiply 42 times 2 so
40*2=80
Its 1 hour and 20 min - its the result
7.2x - 8 = -29.6 that is your answer wrote out in numbers.
Terminal digit filing is a filing system that
works by means of the last two numbers on files to consolidate them. While
middle digit filling uses a tripartite number, using the first part of the
number for the second sort, middle part for the initial sort, and the third portion
for the final sort. One way they are similar is that the two evade working with
large numbers and overpowers the difficulties of crowding at the end of the
storage.
The domain of the function is represented by option C. All real numbers.
