The three angles must add to 180. So x=180-(50+90)= 40 degrees.
Answer:
y = 2x - 3
Step-by-step explanation:
Slope-intercept form is y = mx + b
m = slope
b = y-intercept
If you look at the graph, the y-intercept is on (0, -3) which means the y-intercept is -3.
If you look at the slope, you can use the rise/run method. Let's use 2 as an example. We would turn it into a fraction, 2/1. You then want to use the rise/run method. Starting from the y-intercept, go up the amount of the first number, and then go right the amount of the second number. So we would go up 2 and 1 right.
So this is our answer, y = 2x - 3
Whatever you do to one side you do to he other
Answer:
y = 3x+7
Step-by-step explanation:
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
y = 3x+7
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
