Answer: E
Step-by-step explanation:
Answer: 186%
To get this simply divide 93 into 50 (you will get 1.86 which you can convert to the percentage 186%). An even easier way is to multiply 93 by two (186) since 50% times 2 is 100%. Hope this helps!
Answer:
Step-by-step explanation:
3x+4y=−23.........(1)
x=3y+1 .........(2)
Putting (2) in (1)
3(3y + 1) + 4y = -23
9y + 3 + 4y = -23
9y + 4y = -23 - 3
13y = -26
y = -26/13
y = -2
Putting y into (2)
x=3y+1
x = 3(-2) + 1
x = -6 + 1
x = -5
This is known as quadratic algebra.
To find it, you can use the quadratic formula but that might take a while.
We can factor it out and get
-3(mx² + mx - 1)
We can then set mx² + mx = 1
It would have no solutions
Edit: Above is wrong! I made the mistake of factoring 3 when it cant be factored.
Here is the solution
mx²-3mx=-3
Divide both by -3
mx²+mx=1
And I really messed this up. Its been a long time since quad. Sorry, but I cant seem to get the answer. Try and look up the quadratic formula and see if you can use that
Let's analyze the sequence: {2,3,5,9,17...}.
3 = 2+1
5 = 3+2
9=5+4
17=9+8
So, every element of the sequence is obtained as sum from the previous element + (previous element -1)
y[n]=y[n-1] + (y[n-1]-1)
