I need help on this what is RS

11

Step-by-step explanation:

If RS=TV

5x-9=2x+3

5x-2x=3+9

3x=12

x=4

RS is 5x-9

5(4)-9

20-9

11

attached below is the detailed solution

i) equilibrium solution : y = 0 , y^2 = 1 , y = -1 , +1

ii) attached below

iii) attached below

iv) attached below

v) attached below

Step-by-step explanation:

v) For the sketch of curve attached

red curve ( y(0) ) = -3/2

blue curve ( y(0) ) = 1/2

green solution curve ( y(0) ) = 3/2
