Answer:

Step-by-step explanation:
we have the expression

Convert to vertex form

where
a is the leading coefficient
(h,k) is the vertex
Complete the square


Rewrite as perfect squares

so
The coefficient a =1
The vertex is the point (-2,-2)
When you are on the moon, your mass is 6% of your original weight. 100 divided by 16.6 = 6.024096385542. so orig. M\16.6 = M on moon
Remember the exponential law that says

therefor

the answer is C
X-5=2-3x+9
x-5=-3x+11
4x-5=11
4x=16
x=4
