4 consider the equation cx - d = 2x + 4.
a. replace c in the equation with 2. for what value of d
would the equation have infinitely many solutions? explain.
b. replaced in the equation with 2. for what value
of would the equation have no solution? explain.

The jones farm has 24 cows that each produce 52 quarts of milk a day. how many quarts are produced each day altogether

Which linear equations have an infinite number of solutions? check all that apply.  (x  –  3/7)  =  2/7(3/2x  –  9/14)8(x  +  2)  =  5x  –  1412.3x  –  18  =  3(–6  +  4.1x)(6x  +  10)  =  7(x  –  2)4.2x  –  3.5  =  2.1 (5x  +  8)

(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.
