Astudent submitted the following answer to the graphing systems problem: is that student correct? why or why not? if not, what would the solution be?

No, she is not correct.

Step-by-step explanation:

Since we have given that

First we check the consistency of system of equations:

here ,

so, it becomes,

So, it is consistent and it is an intersecting lines.

So, it would have a unique solution.

From Eq(1), we have,

Put it in eq(2), we have

So, x=4 and

so, the solution point of this line will be (4,12).

No, she is not correct.

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%
