Atoy car is placed at 0 on a number line. it moves 9 cm to the left, then 4 cm to the right, and then 6 cm to the left. what is the total distance the toy car traveled

19 cm

Explanation:

to answer this question, we should remind the difference between distance and displacement:

- the distance covered by an object is the sum of all movements made by the object, regardless of their directions

- the displacement of an object is just the difference in position between its final point and its starting point

Based on these definitions, we can now calculate the distance covered by the car, which has moved 9 cm, then 4 cm and then 6 cm. The distance is just the sum of these values:

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

false

inverse variation is not exponential
