Step-by-step explanation:

y = 2x - 3 \\ plug \: x =  - 1 \\ y = 2( - 1) - 3 =  - 2 - 3 =  - 5 \neq1 \\ hence \: ( - 1, \: 1) \: does \: not \: lie \: on \: the \:  \\ graph \: of \: y = 2x - 3. \\  \\ y = 2x - 3 \\ plug \: x =  1 \\ y = 2 \times 1- 3 =  2 - 3 =  - 1 \\ hence \: ( - 1, \: 1) \:  lie \: on \: the \:   graph \: of \:  \\ y = 2x - 3. \\  \\

The following table shows a portion of a five-year amortization schedule. A 5-year amortization schedule. Loan amount or princip
kogti [31]

The percentage of the payments made were due to interest is 32.6 %. Then the correct option is B.

<h3>What is the percentage?</h3>

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

The following table shows a portion of a five-year amortization schedule.

A 5-year amortization schedule.

Loan amount or principal: 10,900 dollars.

The interest rate on loan: 10. 95 percent.

The table will be

Month         Payment         Principal         Interest         Balance

  15               236.72            155.87            80.85           8704.27

  16               236.72            157.29            79.43           8546.98

  17               236.72            158.73            77.99            8388.25

  18               236.72            160.18            76.54            8228.07

  19               236.72            161.64            75.08            80.66.43

  20              236.72            163.11             73.61             7903.32

Total payment = 6 × 236.72 = $ 1420.32

Total interest = 80.85 + 79.43 + 77.99 + 76.56 + 75.08 + 73.61

Total interest = $ 463.38

Then the percentage will be

\rm Percentage = \dfrac{463.38}{1420.32}*100\\\\Percentage = 32.625 \approx  32.6\ \%

Define and compare radian measure to degree measure
Lelechka [254]
Radian: is the standard unit of angular measure, used in many areas of mathmatics.
degree: is a measuement of plane angle, defined by representing a full rotation as 360 degrees.

Both are two units for measuring angles. There are at least four such units, but degrees and radians are most likely to encounter high school and college.

An item normally $15.99 is listed as being on sale for 30% off its original price, what must you pay?
KengaRu [80]

Answer: a. You must pay $11.19 for the item.

b.The price you would expect to pay would be $36.59

Step-by-step explanation:

Hi, for first the question you need to calculate the 30 percent of the price of the item, and then subtract that result to the original price.

So: $15.99 × 0,30 = $4.797

$15.99 - $4.797 = $11.19

You must pay $11.19 for the item.

  • Question 2:

It´s a similar resolution, first you calculate the 40 percent of the retail price, and then subtract that result to the retail price.

So:

$60.99 × 0,40= $24.396

$60.99 - $24.396 = $36.59

The price you would expect to pay would be $36.59
