-10u^3-16u^2*4u is the answer
Solution:
The standard equation of a hyperbola is expressed as

Given that the hyperbola has its foci at (0,-15) and (0, 15), this implies that the hyperbola is parallel to the y-axis.
Thus, the equation will be expressed in the form:

The asymptote of n hyperbola is expressed as

Given that the asymptotes are

This implies that

To evaluate the value of h and k,
Y=-3/2L -2. At the Y axis, line L is at -2, so we add that as B or the Y intercept. We can see that the graph goes 2 over to the right and down three, which makes the slope negative and 3/2 (rise/run)
Answer:

Step-by-step explanation:

6.40x+9.90(154-x)=1230.90
Solve for x
X=84 for child
154-84=70 for adults
