Answer:
its B.
Step-by-step explanation:
all you have to do is y divided by x to find the constant of proportionality
so it would be two y=2x
Answer:
(5x+3)/2
Step-by-step explanation:
f(x)=(2x-3)/5
f(x)=y
y=(2x-3)/5
interchanging role of x and y
x=(2y-3)/5
5x=2y-3
5x+3=2y
y=(5x+3)/2
the inverse if f(x) = (5x+3)/2

=3/5
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
In a geometric sequence you are just multiplying basically. To go from 36 to 24, you multiply by 2/3, and the same will be with the next term. When you multiply 24 by 2/3 you get 16.
Answer:
the median is 80.5
Step-by-step explanation:
first we put them in order
75,76,77,79,80,81,85,86,90,91
the median is the middle number...however, in cases where there are an even number of numbers, ur gonna have 2 middle numbers....so u take the average of those 2 numbers...basically, u add them and divide by 2.
So we have 2 numbers in the middle.....we add them and divide by 2 to get the median.
(80 + 81) / 2 = 161/2 = 80.5 <== the median
