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
Answer: it is
Step-by-step explanation: the next numbers are 1.5, 3, 4.5.
To answer this item, we let the original speed of the car be x. The time it take to travel a certain distance is calculated by dividing the distance by the speed. Using the condition given above,
189 / (x + 12) = 189/x - 1
The value of x from the equation is 42 mph. Thus, the original speed of the car is 42 mph.
The answer is 21.
2^3 = 8
21 - 13 = 8
