State the order of the given ordinary differential equation.
(1 − x)y'' − 7xy' + 5y = cos x

determine whether the equation is linear or nonlinear by matching it with (6) in section 1.1.

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
