Answer:
See explanation
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

Answer:
x = -1/2, 3/4
Step-by-step explanation:
Step 1: Isolate everything to 1 side
8x² - 2x - 3 = 0
Step 2: Factor
(4x - 3)(2x + 1) = 0
Step 3: Find roots
4x - 3 = 0
4x = 3
x = 3/4
2x + 1 = 0
2x = -1
x = -1/2
8.84/0.68=13 8.84 divided by 0.68 is 13!!!

Answer:
Attaching answer for 1 below!!
2. C. -- y=2x+9
3. B. -- y=5/3x+3
Step-by-step explanation:
1. First screenshot below
2. To convert standard equations (Ax+By=C) to slope intercept (y=mx+b), what you do is preform inverse operations on A to both sides (modeled below). Then, the equation will look like this; By= -Ax+C. The last thing you need to do to cancel out B from the y is divide both sides by B, and you'll have your answer. So, I did that exact process with the equation and that's how I got C. Now, when you have no number next to the y, you don't need to divide, so it's a very simple process that way.
-2x+y=9
+2 +2
3. Same process for 2, except this time we divided by 3.
