This value of "a" is exactly the y-coordinate of the vertex of the parabola
y = x%5E2+%2B+4x++-+31.
To find it, complete the square:
x%5E2+%2B+4x++-+31 = %28x%2B2%29%5E2+-+4+-+31 = %28x%2B2%29%5E2+-+35.
So, this value of "a" is a = -35.
Figure. Plot y = x%5E2+%2B+4x++-+31.
8 books because 77 minus 13 is 64. 64 divided by 8 is 8.
The answer would be A) 14 - 12i
Simplify ( 3 - 7i + 11 - 5i )
Gather like terms ( 3 + 11 ) + ( -7i - 5i )
Simplify ( 14 - 12i ).
16x - 2 - 24x + 4 = -8x + 2

Answer:
The maximum number of hours the school can have the band play at the dance is 4.
Step-by-step explanation:
150 + 100 + 35x ≤ 390
250 + 35x ≤ 390
subtract 250 from both sides
35x ≤ 140
divide by 35 on both sides
x ≤ 4
