What is the point of intersection between the lines x=7 & y=-10

(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.

How many solutions does the nonlinear system of equations graphed bellow have?

X+ y = 5 ; x - y =3 solve using linear combination
