Answer:

(2, 5)

Step-by-step explanation:

Given the 2 equations

y = x + 3 → (1)

- 2x + y = 1 → (2)

Substitute y = x + 3 into (2)

- 2x + x + 3 = 1

- x + 3 = 1 ( subtract 3 from both sides )

- x = - 2 ( multiply both sides by - 1 )

x = 2

Substitute x = 2 into (1) for corresponding value of y

y = 2 + 3 = 5

Solution is (2, 5)

Jim Hunter has decided to retire to Florida in 10 years. What amount should Jim invest today so that he'll be able to withdraw $
ipn [44]
The following formula is applicable;
A=P(1+r)^n

Where,
A = Total amount accrued after 10 years (this is the amount from which the yearly withdrawals will be made from for the 30 years after retirement)
P=Amount invested today
r= Annual compound interest for the 10 years before retirement
n= Number of years the investments will be made.

Therefore,
A= Yearly withdrawals*30 years = $25,000*30 = $750,000
r= 9% = 0.09
n= 10 years

P= A/{(1+r)^n} = 750,000/{(1+0.09)^10} = $316,808.11
Therefore, he should invest $316,808.11 today.

During a sale, a store offered a 15% discount on a tablet computer that originally sold for $460. After the sale, the discounted
Lady bird [3.3K]

The percent of the original price after markup is 98%

<h3>Mark up and discounts</h3>

Given the following parameters

  • Original price of tablet = $460

If during a sale, a store offered a 15% discount on a tablet, the new price after discount will be:

New price = 0.85 * 460

  • New price = $391

If the tablet computer was marked up by 15% after the discount, then the price after the markup is given as:

  • Price after markup = 1.15 * 391
    Price after markup = $450

To get the required percent;

x% of 460 = 450
x% = 450/460

x% = 0.978

x = 98%

Hence the percent of the original price after markup is 98%

What is the area of the shaded region?<br> DO NOT include the unit of measure in your answer
Aleks04 [339]
The area is 73. You have to find the area of both triangles using the formula a = 1/2bh. The shaded triangle is 108 square yards but because another triangle is cut out of it, we need to subtract the area of the white triangle from the shaded triangle. The area of the white triangle is 35. So now we have 108-35 =73. That’s how i got 73.
