15. The answer would be B, because: When x = 2, y = 2*2+3 = 7, and so on, and so forth.
16. The answer would also be B, because: When x = 11, y = 10(11-1) = 100, and so on, and so forth.
Hope this helped! c:
Answer:
Kayla plays on average 0.2 more chess games than Becker
Step-by-step explanation:
The first thing we must do is calculate the mean of each one.
Becker:
(5 + 2 + 4 + 1 + 1 + 4 + 5 + 3 + 2 + 1) / 10 = 2.8
Kayla:
(2 + 3 + 1 + 1 + 4 + 1 + 5 + 3 + 5 + 5) / 10 = 3
if we subtract these averages, we have to:
3 - 2.8 = 0.2
which means that Kayla plays on average 0.2 more chess games than Becker. Since it is not even a complete game, the difference between the two is very small and almost irrelevant.
A) the x-values on the graph are [-2, 4].
all the x-values of the graph are the Domain of the function of the graph. they are found by projecting the graph to the x-axis. check the yellow line in the first picture.
b) all the possible outputs of g are [-1, 3].
all the possible outputs of g, are the Range of g. These are found by projecting the graph to the y-axis. check the red line in the second picture.
c) -1 , 0, 1, 2, and 3 are only a few values in the Range. The range is [-1, 3].
d) we will sketch a graph whose domain is [-2, 4] and range is [-1, 3]. check picture 3
The formula for the area of a parallelogram is
A=b*h where b=base and h=height
plug in the data we know
A=4*5.5
A=22m²
Answer=B
Call Canada's population

, and call the U.S. population

.
We see that

. Substituting 32 million for c, we see that

. Multiplying by ten, we see that

. By using Algebra properly, we have ensured that the number of zeroes in our final answer is correct.
