Answer:
second one
Step-by-step explanation:
just multiply by -9 and see which one fits in
Answer:
A
Step-by-step explanation:
Given a parabola in standard form, y = ax² + bx + c ( a ≠ 0 ), then
minimum/ maximum value is the y- coordinate of the vertex.
The x- coordinate of the vertex is
= - 
y = x² - 
x + 
← is in standard form
with a = 1 and b = - , thus
= - 
= 
Substitute this value into y
y = ( )² - ( ) +
= 
- 
+ = 
Since a > 1 then the vertex is a minimum, thus
minimum value = → A
Answer: 15 players per team
Step-by-step explanation:
Unite rate of players on the team refers to the number of players on each of the teams that the Viking Football league has.

= 150/10
= 15 players per team
Answer: Mustafa is incorrect. He made a mistake in step 2.
Step-by-step explanation: Mustafa was certainly correct in step 1 that x(9x+3) + 3(x+3) is 9x^2 + 6x + 9. However when he was factoring, he made a mistake.
(3x + 3)^2 is NOT equal to 9x^2 + 6x + 9. Rather, (3x + 3)^2 is equal to 9x^2 + 18x + 9. If you want to double check this, use FOIL.
The correct factoring of 9x^2 + 6x + 9 is actually 3(3x^2 + 2x + 3). So, Mustafa made a mistake in step 2.
