Given dy/dt = 2y + 20, check whether each of the following is a solution. Use the approach demonstrated in the example shown above, and in Video: Checking Proposed Solutions of a Differential Equation. • y = 10e^2t - 10 ? This is [ Select ] because dy/dt [ Select ] 2(10e^2t - 10) + 20. • y = 5e^2t - 10 ? This is [ Select ] because dy/dt [ Select ] 2(5e^2t - 10) + 20. • y = 5e^2t - 5 ? This is [ Select ] because dy/dt [ Select ] 2(5e^2t - 5) + 20. Answer 1: a solution Answer 2: is equal to Answer 3: not a solution Answer 4: does not equal Answer 5: not a solution Answer 6: does not equal

Is this solution correct? Describe. The solutions of the equation x^2 + 3x = 18 are x = -3 and x = 0. No, the solution is not correct. There are no solutions. Yes, the solution is correct x=-3 and x=0. No, the solution is not correct. The equation needs to be written in standard form. The solutions are x= -6 and x=3. No, the solution is not correct. x=-18.

Aditya tried to solve the differential equation: dy/dx = 6x - 30 Step 1: integral 30 dy = integral 6x dx Step 2: 30y = 3x^2 + C Step 3: y = x^2/10 + C Is Aditya's work correct? If not, what is his mistake? Choose 1 answer: Aditya's work is correct. Step 1 is incorrect. The separation of variables wasn't done correctly. Step 2 is incorrect. Aditya didn't integrate 30 correctly. Step 3 is incorrect.
