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 = β9
2x + 5y = β6 (6 points)
2x + 5(4y β 9) = β6
2x + 5(β4y β 9) = β6
2(4y β 9) + 5y = β6
2(β4y β 9) + 5y = β6

how can one half x β 5 = one third x + 6 be set up as a system of equations? (6 points)
a) 2y + x = β10
3y + x = 18
b)2y + 2x = β10
3y + 3x = 18
c) 2y β x = β10
3y β x = 18
d)2y β 2x = β10
3y β 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.
