Answer:
11
Step-by-step explanation:
The rate of change is the ratio of the change in Y to the change in X.
When Y changes from -40 to 4, that is an increase of 44 (4--40=4+40=44), so the change in Y is +44. The corresponding change in X is from -3 to 1, so the change in X is +4 (1--3=1+3=4). The ratio of the change in Y to the change in X is 44/4=11.
Try doing the same computation going from the second row to the third row and you will get the same ratio of 11.

Answer:
Correct answer: adult tickets x = 72
Step-by-step explanation:
Given:
x = ? number of the adult tickets
y = ? number of the senior tickets
12$ adult ticket price
8$ senior ticket price
We will solve this problem using a system of two equations with two variables
x + y = 98 we will multiply whole equation with number - 2 and get:
- 2 x - 2 y = - 196
12 x + 8 y = 1072 we will divide the whole equation by the number 4 and get:
3 x + 2 y = 268
- 2 x - 2 y = - 196
we will now add the first equation to the second and get:
3 x - 2 x = 268 - 196
x = 72
x + y = 98 ⇒ 72 + y = 98 ⇒ y = 98 - 72 = 26
y = 26
God is with you!!!
