Answer:
You need $7.09
Step-by-step explanation:
Ex1. 100-92.91=7.09
Ex2. 92.91+7.09=100
Answer:
The relationship is proportional for the turtle and the equation is Distance = 54*Time
Step-by-step explanation:
Turtle’s run:
Distance (meters) | Time (minutes)
108 | 2
405 | 7.5
540 | 10
1768.5 | 32.75
Rabbitt’s run:
Distance (meters) | Time (minutes)
800 | 1
900 | 5
1107.5 | 20
1524 | 32.5
The relationship between distance traveled and time is proportional if this equation is satisfied:
Distance = k*Time or k = Distance/Time
where k is a constant
For the turtle:
108/2 = 405/7.5 = 540/10 = 1768.5/32.75 = 54
Then, the relationship is proportional and the equation is Distance = 54*Time
For the rabbit:
800/ 1 = 800
900/5 = 180
1107.5/20 = 55.375
1524/32.5 = 46.89
Then, the relationship is not proportional.
Standard form of line:
Ax + By = C
where A, B, and C are integers, and A is positive
slope-point form of a line:
y - y1 = m(x - x1)
where m is the slope and (x1, y1) is a point on the line. Replacing with m = 3 and point (2, 5):
y - 5 = 3(x - 2)
y - 5 = 3x - 3(2) distributing
y - 5 = 3x - 6
y - 5 - y = 3x - 6 - y subtracting y at both sides
- 5 = 3x - 6 - y
- 5 + 6 = 3x - 6 - y + 6 adding 6 at both sides
1 = 3x - y which has the standard form
