Answer:

0=  x^{2}+3x

Step-by-step explanation:

Since y= x+1,

x+1=x^{2}+4x+1

--> Bring x to the other side by changing sign.

1= x^{2}+4x-x+1

1= x^{2}+3x+1

--> Bring 1 to the other side by changing sign.

0= x^{2}+3x+1-1

0=  x^{2}+3x+0

(Note: When there's is no number in the LHS side, it becomes 0)

--> Bring 0 on the RHS, to LHS

0-0= x^{2}+3x

--> 0=  x^{2}+3x

Please mark me as brainliest!

An account earns 10% annual compound interest. The amount in the account after t years is equal to the principal times the expre
Katarina [22]
Assuming that means 1.10^t:

0.10 is for years. To get months divide by 12.
0.10/12 = 0.0083333... 
And (1+0.083333...) = 1.0833333. (You will have to multiply t by 12 also to get it in terms of months)
(1.0833333)^12t

A sequence is defined recursively by the formula f(n + 1) = f(n) + 3 . The first term of the sequence is –4. What is the next te
ExtremeBDS [4]
F(n+1) = f(n) + 3 indicates that we add 3 to the previous term to get the next term

So,
next term = (previous term) + 3
second term = (first term) + 3
second term = (-4) + 3
second term = -1

Making the answer to be choice B) -1
