Answer:
Option B.
Step-by-step explanation:
Inverse function:
Suppose we have a function y = f(x). To find the inverse function, we exchange x and y on the original function, and then isolate y.
The domain of the inverse function(x values) is the range of the original function(y values).
Original function:
Domain is , and when . So the range is , that is,
Inverse function:
Exchanging x and y
The inverse function is
Domain:
Range of the original function is , so the domain of the inverse function is . The correct answer is given by option B.
Step-by-step explanation:
x=8-y
2x-y=7
2(8-y)-y=7
16-2y-y=7
-3y=-9
y=3
x=8-y
x=8-3=5
Answer:
B
Step-by-step explanation:
2/6 x d = 388
d = 388 x 6/2 = 1164 m
Karin and Cheryl do not have the same average actually. I know this because, just because Cheryl and Karin have the same numbers in their average does not mean they literally HAVE the SAME average. Think about it this way, if you take out the zero and the decimal in both of their averages, Cheryl's average is 340. Karin's is 304. If you think about it in hundreds...Cheryl has a better average then Karin. So therefore, Cheryl's average is more than Karin's, so they do not have the same average.
Hope this helps!!
Answer:
9.7p-15
Step-by-step explanation:
8.2p−4.3−10.7+1.5p
=8.2p+−4.3+−10.7+1.5p
=8.2p+−4.3+−10.7+1.5p
=(8.2p+1.5p)+(−4.3+−10.7)
=9.7p+−15
9.7p−15
Hope this help :)
