Zinaida [17]
Answer:
{1, 2, 3, 4, 6, 8, 9, 10, 12, 14, 15, 18, 21}
Step-by-step explanation:
A∪B is A union B
which is the elements that appear in either set
Answer:
all real number greater than or equal to -3.
It is the average distance between each data value and the mean<span>.</span>
Here the topic is "functions." Roughly speaking, we have a box. Input enters at one end and output exists at the other. Now, if every input value x (such as 2) is doubled by the box, every output value is 2x: (0,0), (1,2), (2,4), etc.
We call this "doubling" a "constant rate of change.
If you plot the points given, you'll see that they all are on a straight line. That straight line has the slope 2: y = 2x. Again, 2 is the "constant rate of change" here.
If you drive at a steady 55 mph, you are covering 55 miles during every hour behind the wheel. Again, 55 is a "constant rate of change."
