The

symbol means intersection, so everything that is in both sets, and the

symbol means union, so the two sets combined.


So the answer is A.
<h2>Answer</h2>
f(x) = 5(1.25)x + 4
<h2>Explanation</h2>
To solve this, we are going to use the standard exponential equation:

where
is the initial amount
is the growth rate in decimal form
is the time (in months for our case)
Since the hours of classic music remain constant, we just need to add them at the end. We know form our problem that Sue initially has 5 hours of pop, so
; we also know that every month onward, the hours of pop music in her collection is 25% more than what she had the previous month, so
. Now let's replace the values in our function:



Now we can add the hours of classical music to complete our function:

Make an absolute value function, (coordinates are all (1,1), (2,2), (-5,5) (-1,1) etc.) and shift all the points up by 2 on the y-axis
51 is the interquartile range for the set of data hope this helps;)
Step-by-step explanation:
x=17/5 - 2/7
LCM is 7*5=35
x= (17*7-2*5)/35=109/35
