Option C: -3 is the average rate of change between and
Explanation:
The formula to determine the average rate of change is given by
Average rate of change =
We need to find the average rate of change between and
Thus, from the table, we have,
,
,
Thus, substituting these values in the formula, we get,
Average rate of change =
Thus, the average rate of change between and is -3.
Hence, Option C is the correct answer.
Answer:
5/3
Step-by-step explanation:
The opposite of a number always has to have the same distance from zero, positive or negative. So in this case, since -5/3 is a negative fraction, the answer would be 5/3. This fraction may be positive but they have the same distance from zero.
Let be "x" the number of colored pencils in the box.
According to the information given in the exercise, there are 84 pencils in the box and 53 of them are regular pencils.
Knowing this information, you can set up the following equation:
Finally, you have to solve for the variable "x" in order to find its value. In order to do this, you can apply the Subtraction property of equality by subtracting 53 from both sides of the equation:
The answer is: There are 31 colored pencils in the box.
