38+7k=8(k+4)
3(1-3x)=2(-4x+7)

K = 6      X = -11

Step-by-step explanation:

38+7k=8(k+4)                  3(1-3x)=2(-4x+7)

38 + 7k = 8k + 32               3 - 9x = - 8x + 14

     - 7k    -7k                    - 3                   -  3

 38 = k + 32                        -  9x = - 8x + 11

- 32      - 32                         + 8x   + 8x

        k = 6                             - 1x = 11

                                               -1     -1

                                                x = -11

required rate of return = 0.166 = 16.6%

step-by-step explanation:

under the capital asset pricing model (capm), the required or expected rate of return for a particular security or asset is given using the formula:

required rate of return = risk-free rate + beta*(market risk premium)

we are given that;

risk-free rate = 4% = 0.04

beta = 1.4

market risk premium = 9% = 0.09

we simply plug these values into the above formula;

required rate of return = 0.04 + 1.4*(0.09)

required rate of return = 0.04 + 0.126

required rate of return = 0.166 = 16.6%
