How could you change this system so that it has no solution?
-x+y=-4
-x + 2y = -10
Write your new system AND explain why it is
inconsistent.
HELP!!!

(a) compute the maclaurin polynomial m2(x) for f(x) = cos x. (b) use the polynomial of part (a) to estimate cos π 12. (c) use a calculator to compute the error made using the estimate from part (b) for the value of cos π 12. remember that the error is defined to be the absolute value of the difference between the true value and the estimate.

Prove that (x-2)is factor of p (x)=2x³-3x²-17x+30

Find the maximum value of p= 4x + 5y subject to the following constraints :
