if you were to use the substitution method to solve the following system, choose the new equation after the expression equivalent to x from the first equation is substituted into the second equation.

x + 4y = βˆ’9
2x + 5y = βˆ’6 (6 points)

2x + 5(4y βˆ’ 9) = βˆ’6
2x + 5(βˆ’4y βˆ’ 9) = βˆ’6
2(4y βˆ’ 9) + 5y = βˆ’6
2(βˆ’4y βˆ’ 9) + 5y = βˆ’6

how can one half x βˆ’ 5 = one third x + 6 be set up as a system of equations? (6 points)

a) 2y + x = βˆ’10
3y + x = 18
b)2y + 2x = βˆ’10
3y + 3x = 18
c) 2y βˆ’ x = βˆ’10
3y βˆ’ x = 18
d)2y βˆ’ 2x = βˆ’10
3y βˆ’ 3x = 18

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