Answer:
x represent the value loaned at 15% and y represent the value loaned at 10%.
and 
Step-by-step explanation:
We are going to write a system of two linear equations. The first equation will represent the total amount loaned.
Now the second equation are will represent the interest earned for both loans.
Then x represent the value loaned at 15% and y represent the value loaned at 10%. Now solving the equation system we have:
using this in the other equation to find y
With the value of y we can find x
(5x-3)(4x+5) the last step you have to look at the two terms that you are adding together the 4x(5x-3) and the 5(5x-3) and see what is similar. well the whole bracket is the same the 5x-3 so factor that out and collect the other leftover terms so the 4x and the +5 and thats what goes in the second bracket
Answer:
Neither
Step-by-step explanation:
2,5,10,17
Differences between numbers:
2->5 (3)
5->10 (5)
10->17 (7)
There is no common difference between numbers so its neither.
a4 is 17 because that is the 4th term in the sequence.
