2. Prove that the functions in the right-hand column below are solutions of the differential equations in the left-hand columns. (Be sure to state the common interval for which solution and differential equation make sense.) (a) y' + y = 0 (b) y' = e 1 √1-x² f"(x) (c) dx2 (d) f'(x) (e) xy' (f) (1+x²)y dr (α) 008 A 2y = xy 2r sin A - 0 y = e-*. y = e*. y = x Arc sinx+√1-x². y = e² + 2. x². y = y = √1+x². a sec² A

Convert the given Fahrenheit temperature to its equivalent temperature on the Celsius scale. Use C = (F-32) or F=C+32, where F is the degrees in Fahrenheit and C is the degrees in Celsius. 73°F 73°F=°C (Round to the nearest tenth as needed.)

i cant seem to understand the answer. could you please retype or send a picture?
