Suppose that the sequence x0, x1, x2... is defined by x0 = 5, x1 = 6, and xk+2 = 5xk+1−6xk for k≥0. Find a general formula for xk. The right answer is: xk = −4(3k)+9(2k)

But how do we get that answer? Please show all your steps with explanation.

Which of these equations, when solved, gives a different value of x than the other three? a9.1 = -0.2x + 10 b10 = 9.1 + 0.2x c10 – 0.2x = 9.1 d9.1 – 10 = 0.2x

Dakota earned $7.50 in interest in account a and $18.75 in interest in account b after 15 months. if the simple interest rate is 4% for account a and 5% for account b, which account has the greater principal? explain. to make it a little easier, there is an image. good luck!

If x is 6, then 7x= a. 13 b. 42 c. 42x d. 76
