Compute (a) δ y and (b) dy for the given values of x and dx=δx y=9−x^2, x=−2 ,δx=.4

Consider the system: y = 3x + 5 y = ax + b what values for a and b make the system inconsistent? what values for a and b make the system consistent and dependent? explain

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