Louisa has earmarked at most $250,000 for investing in two companies involved in the production of renewable energy: Solaron Corporation and Windmill Corporation.
She specifies that at least $50,000 must be invested in each company and that the amount invested in Solaron Corporation must not exceed 120% of that invested in Windmill Corporation.
(a) Write a system of linear inequalities that gives the restrictions placed upon Louisa's investments. (Let x represent the amount in thousands of dollars that Louisa invests in Solaron Corporation, and let y represent the amount in thousands of dollars she invests in Windmill Corporation.)

the inequalities are

x + y ≤ 250000

x ≥ 50000

y ≥ 50000

x ≤ 1.2y

Step-by-step explanation:

Let x represent the amount in thousands of dollars that Louisa invests in Solaron Corporation.

let y represent the amount in thousands of dollars she invests in Windmill Corporation.

Louisa has earmarked at most $250,000 for investing in two companies involved in the production of renewable energy. The inequality is

x + y ≤ 250000

She specifies that at least $50,000 must be invested in each company. It means that

x ≥ 50000

y ≥ 50000

The amount invested in Solaron Corporation must not exceed 120% of that invested in Windmill Corporation. It means that

x ≤ 1.2y

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
