Answer:
Points C,D, E and F are coplanar.
The largest possible value of b is 10, since for some x = x₀ it could be the case that f(x₀) = -5 and g(x₀) = -2; then f(x₀) g(x₀) = -5 × -2 = 10.
0.5 is the first way
1/2 is the second way
50% is the third way.
Hope that helps bud :).
Answer:
(C) 18
Step-by-step explanation:
We can create a systems of equations. Assuming 
is Michelle's age, 
is Joan's age, and 
is Ryan's age, the equations are:
We can use substitution, since we know the "values" of m and j.
So we know that Joan is 18 years old.
