Following linear system:
(a-1)x + (3a+1)y + 2z = b^2
(a-1)x + (4a-2)y + (a+3)z = -3
2x + (3a+1)y + 3(a-1)z = 2b
a) possible values of a and b so the system has a unique solution.
b) corresponding values of a and b so the system have no solution n infinitely many solutions respectively.

Two consecutive numbers(from 0 to 9) are given to A and B.if A is asked about B's number he says"i don't know B's number", then B is asked about A's number, he says "i don't know A's number". Then A says"i know B's number".Find A's and B's number.

A $50,000 loan is to be amortized over 7 years, with annual end-of-year payments. Which of
these statements is CORRECT?
a. The annual payments would be larger if the interest rate were lower.
b. If the loan were amortized over 10 years rather than 7 years, and if the interest rate
were the same in either case, the first payment would include more dollars of interest
under the 7-year amortization plan.
c. The proportion of each payment that represents interest as opposed to repayment of
principal would be lower if the interest rate were lower.
d. The last payment would have a higher proportion of interest than the first payment. e.
The proportion of interest versus principal repayment would be the same for each of
the 7 payments.

I'm trying to rearrange the equation below to solve for the value of I. But I can't get it out of the second factor:
T = (W*L / 2*I) * (L-squared * I-squared * H-squared - 2 * I * H) quantity square rooted
(Sorry for the weird way of spelling it out. This !@#$%^&* yahooty won't let me use math symbols...)
I'm trying to solve for I in this tower guy tensioning formula thet uses the visual guy sag calculating method. The value of I represents the intercept distance below the guy attachment point on the tower and a visually observed point on the tower with a transit connected to the guy cable at the anchor to establish the guy starting angle and amount of sag resulting after tensioning, The guying distance to the tower, L, the height of the guy connection point, H, and the length and weight of the cable, contained in W, are known. T is the tension.
