Answer:
The positive difference between the a values is 0.5
Step-by-step explanation:
we know that
Both parabolas cross the x axis at (-4,0) and (6,0)
so
The general equation is

<em>Find the value of a in the first parabola</em>
The y-intercept is (0,-12)
so
For 
substitute




<em>Find the value of a in the second parabola</em>
The y-intercept is (0,-24)
so
For 
substitute




<em>Find the positive difference between the a values for the two functions</em>
so

Answer:
48%
Step-by-step explanation:
P (not getting a speckled rock) = 12/18 = 2/3
P (not getting a green rock) = 13/18
2/3 * 13/18 = 26/54 = 13/27 ≈ 48%
Answer:
Step-by-step explanation:
9m-3(m+6)=2(m+1)
9m - 3m - 18 = 2m + 2
6m- 18 = 2m +2
4m = 16
m= 4
You would multiply 2x4 and 3x4 and it would be 8/12 so that leaves you with 4 twelths left.
