Suppose a+b=2a. which one of these expressions equals b−a? choose 1 1) 2b 2) 2a 3) a-b 4) -2b 5) -b squared

Hello from MrBillDoesMath!

NONE of the provided answers.

Discussion:

a + b = 2a    =>                             (given)

(a - 2a)  + b =  2a - 2a = 0            (subtract 2a from both sides)

-a + b = 0 =>

b - a =0  

which is NONE of the provided answers.

P.S.  I'll be on vacation from Friday, Dec 22 to Jan 2, 2019. Have a Great New Year!

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.

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%
