Hello there!
So there are two separate problems: 9 * (11-4) and 3 * (11-4). To find the value for each expression, use order of operations. We'll solve what's in the parenthesis before multiplying that value by the other number. 11-4 is 7. 7 * 9 is 63. 11-4 is 7. 7 * 3 is 21. You can divide 63 by 21 to get 3. This means that 9 * (11 - 4) is three times as much as 3 *(11 - 4). Even just by looking at the problem, the expression in the parenthesis is the same thing, but the front numbers are different. 9 is three times as much as 3. The answer is A.
For the book store, it is a discreet graph. Every book is a case by itself, no event is dependent on the other. So now variable is dependent on another.
The swimming pool case, the time is the independent variable in the function where the water volume changes with respect to time. So it it has a continuous graph.
Hope this helps.
There are 6 sides, with 6 numbers. A number less than 5 is 4/6, or simplified, 2/3.
