Macy has a 20 year adjustable rate mortgage with a fixed rate for the first 7 years. in the 8th year, the interest rate rises to 6.2%. the remaining balance at the end of the 7th years is $398,381.20. what is the monthly payment in the 8th year?

The table shows the balance of a money market account over time. write a function that represents the balance y(in dollars) after t years.

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

It says factor each expression completely 8y+48
