Step-by-step explanation:
y = -2x² + 4x + 1
Complete the square.
y = -2 (x² − 2x) + 1
y = -2 (x² − 2x + 1) + 1 − (-2)(1)
y = -2 (x − 1)² + 3
The vertex is (1, 3). The leading coefficient is negative, so the vertex is a maximum.

Answer:
Just cut it in half. <3
Step-by-step explanation:
If you cut it in half, Bart gets some and his friend. (Im horrible at explaining sos!!)
For example, y = k/x; when x = 3 => k = 3y; when y = 9 => k = 27 and x = 27/9 = 3;
The answer is 3!
Answer:
26 and 32. The product (multiplied together) is 832.
Answer:
$74.50
Step-by-step explanation:
Using their given equation, y = 2.50x + 12, we can substitute 25 for x in order to solve it.
y = 2.50x + 12
y = 2.50(25) + 12
y = 62.50 + 12
y = 74.50
Therefore, Marty pays $74.50 for the total price if he rents 25 movies.
