Bob - 8(s + 2)

8(6.25 + 2) = 66

If a jelly bean machine contains 16 pink jelly beans, 34 blue jelly beans, 24 black jelly beans, and 26 purple jelly beans, what
Viefleur [7K]
Well out of 100 jelly beans 24 are black so it would be a 24 out of 100 chance to pick a black jelly bean. But that can be simplified down to a 6 out of 25 chance. So your answer is 6/25. Hope this helped. ;)

What’s the axis of symmetry and the vertex of x^2-4x-32
konstantin123 [22]
<span>x^2 -4x -32
</span>a =1b= -4c= -32
The x,y points of the vertex are usually referred to as Vertex = (h, k)where h = -b / (2 * a)
h = --4 / (2 * 1)h = 4 / 2h = 2
k = ah^2 +bh + ck =1*4 -4*2 -32k = 4 -8 -32k = -36
vertex = (2, -36)axis of symmetry = x position = 2

Solve for x: k=3x+2/x-1
Anna11 [10]

Answer:

x = (2+k)/(k-3)

Step-by-step explanation:

k = (3x +2)/(x-1)

First just multiply both sides by (x-1)

(x-1)k = 3x+2

kx - k = 3x+2

Add k both sides and Subtract 3x both sides to get:

kx - 3x = 2+k

Take x out since it's common

x(k-3) = 2+k

Multiply both sides by (k-3)

x = (2+k)/(k-3)

Hope this helps!
