Answer:
Step-by-step explanation:
58 is the answer without tax
so the cost of an adult ticket is 13 dollars
and the kids ticket is 8 dollars
use system of equations to solve this.
58=2x+4y
y=x-4
T=2
t^2=4
4-4=0
is that right?
Answer:
x=15
Step-by-step explanation:
Divide both sides by the numeric factor on the left side, then solve.
Answer:
13.92
Step-by-step explanation:

We first obtain the equation of the lines bounding R.
For the line with points (0, 0) and (8, 1), the equation is given by:

For the line with points (0, 0) and (1, 8), the equation is given by:

For the line with points (8, 1) and (1, 8), the equation is given by:

The Jacobian determinant is given by

The integrand x - 3y is transformed as 8u + v - 3(u + 8v) = 8u + v - 3u - 24v = 5u - 23v
Therefore, the integration is given by:
