Answer:
A. a=12, b=63.c =36
Step-by-step explanation:
<span>proportional function equation is <span>y = kx
x = age
y = dollars
k = amount per
Q18
I believe father side would be y = 5x
mother side would be y = 2x
Q19
at 16 they would receive 80 from father side
and receive 32 from mother side
which is a difference of 48dollars.

Let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3
Then the equation is (x-x₁)(x-x₂) = 0
If you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.
You can see that a=1 (there is just an x²)
b = (-5 -2√7 + 2√7 - 5)/3 = -10/3
c = ((-5-2√7)/3 ) * (-5+2√7)/3) = -1/3
So the equation you're looking for is:
The answer is b because you must simplify
