f(x) = -4x2 - 16x - 11 a = -4, b = -16, c = -11 x-coordinate of the vertex = -b/2a = -(-16)/2(-4) = 16/-8 = -2 y-coordinate = f(-2) = -4(-2)2 -16(-2) - 11 = -16 + 32 - 11 = 5 vertex is (-2, 5)
√(16x) = 4√x = 4x1/2
16x - 8x + 12 = 78 + 22 or simplified to (16x-8x=8x)(78+22=100) 8x + 12 = 100 Simplify some more (Subtract 12 from both sides) 8x = 88 Divide both sides by 8, and x = 11
16x/100 = 3564.28 Multiply both sides by 100: 16x = 356428 Divide both sides by 16: x = 22276.75
16x = 55Therefore, x = 55/16x = 3.4375
16x-8x+12 = 78+22 16x-8x = 78+22-12 8x = 88 x = 11
(x - 5)(x - 11)
16x + 2 - 8 = 16x + 24 implies 16x - 6 = 16x + 24 subtracting 16x from both sides, this implies: -6 = 24 So the equation has no soultions.
16x + 2 - 8 = 16x + 24 implies 16x - 6 = 16x + 24 subtracting 16x from both sides, this implies: -6 = 24 So the equation has no soultions.
16x-32 = -16
15x-16x = -1
sqrt[(16x)4] = (16x)2 = 256x2
[(-16x)12]1/3 = (-16x)4 = 65536x4
16x+y
16x subtracted by 25xy = -9
1-16x speed = -15
