R(x)= -x2+3x is x=0
s(x)= 2x+1 is x= -1 over 2

I’m not sure what the answer is but you can use an app called Socratic Will help you out
The commutative property of multiplication states that u can " commute " the numbers, move them around, and the result will still be the same.
Example : 2 * 4 = 4 * 2
Therefore, mn = nm
<u>Answer:</u>
The correct answer option is D. 0.42.
<u>Step-by-step explanation:</u>
We are given the results of a survey in which people were asked if they prefer reading books or e-books.
We are to find the marginal frequency of the number of people who prefer to read books.
For that, we will divide the total number of people who prefer reading books by the total number of people surveyed.
Marginal frequency = 105/250 = 0.42
1)3/5
2)7/20
3) 7/5
because you just pit them all over 100 and since they are all divisible by 5 you divide them by 5
