Answer:
It is incorrect. The product is 3/2.
Step-by-step explanation:
The factored form of a quadratic with roots p and q can be ...
a(x -p)(x -q) = ax² -a(p+q) +apq
Then the product of the roots is the ratio of the constant to the leading coefficient:
pq = (apq)/a
In the given quadratic, that product is ...
pq = 3/2 . . . . . . not 5/2
The statement that the product of roots is 5/2 is <em>incorrect</em>. That value does not have the required relationship to the coefficients of the quadratic.
the original fraction would be 4:5 divided by 2 and 1 making the answer clear and then what you do is take your answer multiplying it by the improper fraction and subtracting it by the mixed and the others that you should know and then you get your real answer.
Have a good day!
It might seem confusing but it is actually correct, how do i know?

Answer:
y=-1/2 x +13
Step-by-step explanation:
negative reciprocal of 2 is -.5 and then find what y intercept it would be to go through that point
Answer:
Therefore, x = -2m+4/-n-1
Answer:
It is 437.5
Step-by-step explanation:
The median refers to the value in the middle of a set of number or observation. If the set is uneven, the value is one of the numbers, if the number of observation is even, then is the average between the two numbers in the middle.
In this set, we know that on upper shelf the maximum number is 400 pages. So all the other books contain less pages than or equal amount of pages to the book with 400 pages.
On the lower shelf the books have at least 475 pages.
So we can express our sets in this way
Upper shelf (x ; 400)
Lower shelf (475 ; Y)
The median of the number of pages between this 2 shelves is the number between 400 and 475.
So it is 437.5
