Answer:
The rate of change represented in the table is 14
Step-by-step explanation:
rise over run or y2-y1/x2-x1 to find the rate of change
pick two points
lets use (0,-11) and (2, 17)
17 - (-11) / 2 - 0
= 28 / 2
= 14
well, we know it's a rectangle, so that means the sides JK = IL and JI = KL, so
52 tickets cost $10 and 18 tickets cost $12
10x+12y=804. (1)
x+y=70. (2)
From (2)
x=70-y
Substitute x=70-y into (1)
10x+12y=804
10(70-y)+12y=804
700-10y+12y=804
700+2y=804
2y=804-700
2y=104
y=104/2
y=52
Recall
x+y=70
x+52=70
x=70-52
x=18
