Connect arcs that are above the original line with a straightedge ⇒ 2nd
Step-by-step explanation:
* <em>Lets revise how to construct a perpendicular line through a point</em>
<em> on the line</em>
- <u>Given:</u> line AB and point P lies on it
1. Place your compass pin at P and draw an arc of any size below
AB that crosses the line twice at points C and D
2. Stretch the compass to a larger distance
3. Place the compass pin on point C and draw a small arc above
the line
4. Without changing the distance of the compass place the
compass pin on point D and draw another small arc intersects
the small arc from C at point E
5. <u>Using a straightedge, to join P which is on the original line and E </u>
<u>which is the intersection point of the two small arcs above the </u>
<u>original line,</u> then PE is perpendicular to AB at E
- From the steps up the step is including in the construction of a
perpendicular line through a point on a line is:
<u><em>Connect arcs that are above the original line with a straightedge</em></u>
* <em>Remember:</em>
- The step of Connect arcs that are above and below the given line
with a straightedge is in the construction a perpendicular from a
point off the line
- The step of Create arcs on either side of a point that is off the
given line is in the construction of a perpendicular bisector
of a line
- The step of Create a copied angle by using the first two lines as the
original angle in the construction of the parallel lines

Step-by-step explanation:
Let be the number of students and
be the number of adults on the show.
1. Tickets cost $15 for students, so x student tickets cost $15x.
Tickets cost $25 for adults, so y adult tickets cost $25y.
Total cost of all tickets is $(15x + 25y).
The charity show is conducted in order to raise at least $3,750, thus
2. The auditorium can accommodate up to 180 spectators, hence
3. We get the system of inequalities:
Plot all solutions sets to each inequality and the common region is the solution set to the system of inequalities. This region is not empty, so the charity will reach its goal. For example, if they sell 50 students tickets and 125 adult tickets, they will raise
