-3x^2 + 12x -6
a = -3
b = 12
We calculate the vertex "x" value with this formula:
(vertex "x value") = -b / (2*a)
(vertex "x value") = -12 / -6
The vertex "x" value equals the axis of symmetry value.
The axis of symmetry is at x = 2.

10!=3628800
10-3=7
7!=5040
3628800/5040=720
Use the slope formula
and plug in the values for x and y.
4 consecutive odd integers...
x, x + 2, x + 4, x + 6
(x) + (x + 2) + (x + 4) + (x + 6) = 232
4x + 12 = 232
4x = 232 - 12
4x = 220
x = 220/4
x = 55
x + 2 = 55 + 2 = 57
x + 4 = 55 + 4 = 59
x + 6 = 55 + 6 = 61
so ur numbers are : 55, 57, 59, 61
Answer:
$6.49
Step-by-step explanation:
Pennies = 8% of 50 =4 ; 4x0.01 = 0.04
Dimes = 30% of 50 = 15 ; 15x0.10 = 1.50
Nickels = 10 + 4(number of pennies) = 14; 14x 0.05 =0.70
Quarters = 50 - 33 (total pennies + dimes + nickels ) = 17 ; 17x0.25=4.25
Therefore total amount in bag = 0.04+1.50+0.70+4.25 = $6.49
