Answer is D:
e + 5 = 3e - 11
2e = 16
e = 8
Ella is 8 years old
Jamie is 8+5 = 13 years old
Answer:
x={-2,2}
Step-by-step explanation:
Graph them when intersecting.
Algebraically:
x^2 + 1 = -x^2 + 9
Add x^2 on both sides and subtract 1 on both sides.
2x^2 = 8
Divide 2 on both sides
x^2 = 4
Square root on both sides
|x| = 2
Remove abs value by putting + or - on the other side
x = {-2,2}

The cubic function is 
Option D is correct
Step-by-step explanation:
We need to find the cubic function with the given zeros -6,7,-4
If -6,7,-4 are zeros of the function then:
x=-6, x=7 and x=-4
=> x+6=0,x-7=0 and x+4=0
Multiplying these terms to find the cubic function:
(x+6)(x-7)(x+4)
Solving:

So, the cubic function is 
Option D is correct
