Answer:

The solution sets are (\frac{1}{3},\frac{5}{3}) and (5,-3)

Explanation:

We are given two equations and we are supposed to solve these two equations and find their solutions.

x + y = 2

4y^{2}-x^{2}=11

Substitute the first equation in the second and make it a quadratic equation in one variable.

4y^{2}-(2-y)^{2}= 11

4y^{2}-(y^{2}-4y+4)=11

3y^{2}+4y-4=11

3y^{2}+4y-15=

3y^{2}+9y-5y-15=0

(3y-5)(y+3) = 0

y = \frac{5}{3} or y = -3

x = \frac{1}{3} or x = 5

The solution sets are (\frac{1}{3},\frac{5}{3}) and (5,-3)

BartSMP [9]

Year 1 = 35.23 days

Year 2 = 44.64 days

<h3>What are net sales?</h3>
  • Net sales are calculated by deducting appropriate sales returns, allowances, and discounts from gross revenue.
  • Net sales costs have an impact on a company's gross profit and gross profit margin, but net sales exclude the cost of goods sold, which is typically a key driver of gross profit margins.
  • Net sales are operating revenues obtained by a corporation for selling its products or performing its services in bookkeeping, accounting, and financial accounting.
  • They are recorded directly on the income statement as Sales or Net sales and are also known as revenue.

So, Days' Sales Uncollected = Accounts receivable / Net Sales * Days

Year 1 = $64,000 / $663,000 * 365 days = 35.23 days

Year 2 = $91,000 / $744,000 * 365 days = 44.64 days

Therefore,

Year 1 = 35.23 days

Year 2 = 44.64 days
