Answer
Rebecca has 76 comic books
Maurice has 54 comic books
Step-by-step
Since there are 54 fewer comics and together they have 130 comics, you should subtract 54 from 130. Once you do that your answer will be 76; and that is how many comics Rebecca has. And 76+54=130 so Maurice has 54 comics
There are 8000 millimeters because 1 liter is also 1000 millimeters

- Range is the set of y-values that are outputted by function f(x)
Step-by-step explanation:
When we graph the equation, we should see that our y-values span from -∞ to 0. Since 0 is a closed dot, it is inclusive in the range:
(-∞, 0] or y ≤ 0
To find the minimum, take the derivative of the function and equate to zero:
f(x) = y = x² + ax + b
dy/dx = 2x + a = 0
Substitute x =6:
a = -2x
a = -2(6)
a = -12
Then, substitute x = 6, y = 7 and a = -12 to find b.
7 = (6)² -12(6) + b
7 + 36 = b
b = 43
Thus, a = -12 and b = 43
