Answer:
They have the same maximum.
Step-by-step explanation:
Function 1: y = 4x^2 is symmetrical about the y axis so its maximum value is when x = 0, which is 9.
Function 2: The graph passes through 0, 9 (given) and the x intercepts (-2,0) and (2, 0) are equidistant from the origin so it is also symmetrical about the y-axis and it's maximum is also 9.

Answer:
40
Step-by-step explanation
If it goes from 5 weeks to 10 weeks (doubled), and there were 20 quizzes in 5 weeks, then the quiz amount (20) should be doubled to 40.
Answer:
6 3/4 (six and three fourths)
Step-by-step explanation:
First, we must turn 4 6/7 into an improper fraction, AKA 28/7. Now, you can't subtract 1/4 from 28/7, can you? So what you need to do is find the greatest common factor of 4 and 7. The GCF would be 28 (7 x 4 = 28, 4 x 7 = 28).
Now we know that the GCF is 28, we can turn the numbers into 28/28 and 1/28. But wait! We aren't done yet. Now we have to change the numerators. Since you multiplied the denominator (7) by 4 to get 28, you must now multiply 28 by 4 as well. (If you do something to the bottom, you have to do it to the top!) Because of this, we are now at 196/28.
Next, we must do the numerator of 1/28. Since we multiplied the denominator (4) by 7 to get 28, we must now multiply 1 by 7. This gets you to 7/28.
It's finally time to subtract. 196 - 7 is 184, so we are at 184/28. But hey, that's an improper fraction! You have to simplify. 184 divided by 28 is 6.75. 0.75 is 3/4 when turned into a fraction.
Mash 6 and 3/4 together, and you've got your answer! 6 3/4.
