Step-by-step explanation:
The parametric equations of the circular cylinder are:

If the orientation of the cylinder is changed to have the height
along the x-axis, the parametric equations of the cylinder match:

The parametric equations of the circular paraboloid are:

Using the units vectors the parametric equations match:

The parametric equations of the cone are:

Using the units vectors and rotating the base of the cone from
to
the parametric equations match:

The equation left is the equation of a plane:

Let S represent the cost of a small box, and L represent the cost of a large box.
Matt's sale can be represented by the equation
3S +14L = 203
Ming's sale can be represented by the equation
11S +11L = 220
There are a number of ways to solve a pair of equations. One is to graph them. The graph shows the costs to be ...
The cost of a small box of oranges is $7. The cost of a large box of oranges is $13.
Answers:
bio = 258
sociology = 169
============================================================
Work Shown:
x = number of bio textbooks
y = number of sociology textbooks
x+y = 427 books sold total
y = x-89 since 89 less sociology textbooks were sold compared to bio
Apply substitution to get the following
x+y = 427
x+x-89 = 427 ... replace y with x-89
2x-89 = 427
2x = 427+89
2x = 516
x = 516/2
x = 258 bio textbooks were sold
y = x-89
y = 258-89
y = 169 sociology textbooks were sold
