Trevon’s school is selling tickets to a fall musical. On the first day of ticket sales the school sold 13 adult tickets and 12 s

Answer:

adult: $7
student: $10

Step-by-step explanation:

Let a and s represent the prices of adult and student tickets, respectively.

13a +12s = 211 . . . . . . ticket sales the first day

5a +3s = 65 . . . . . . . ticket sales the second day

Subtracting the first equation from 4 times the second gives ...

4(5a +3s) -(13a +12s) = 4(65) -(211)

7a = 49 . . . . . . . simplify

a = 7 . . . . . . . divide by 7

5(7) +3s = 65 . . . . substitute into the second equation

3s = 30 . . . . . . . subtract 35

s = 10 . . . . . . . divide by 3

The price of one adult ticket is $7; the price of one student ticket is $10.

Find the orthocenter of the triangle with the given vertices: L(2, 2), M(-4, 2), N(-2, 6) a (-2, 4) b (3, -5) c (2, -4) d (-3, 5

Answer:

(a) (-2, 4)

Step-by-step explanation:

The orthocenter is the point of concurrence of the altitudes of the triangle.

A plot of the triangle vertices shows the triangle to be acute. That means the orthocenter is inside. This eliminates choices B, C, D, which are all points outside the triangle.

Conveniently, side LM is horizontal. This means the orthocenter will have the x-coordinate of the vertical line through N, which is -2. Only one answer choice has an x-coordinate of -2:

a (-2, 4)
