Using the given points determine ∆y. (-3,-5) and (0,10)

1 answer:

4 0

If the question is only asking for the difference between the y in the two points, then the difference can be simply calculated as y2 - y1 as follows:
<span>∆y = y2 - y2 = 10-(-5) = 15 units

If the two given points are to be used to determine the slope of a line, then the slope can be calculated as follows:
slope = (y2-y1) / (x2-x1) = (10--5) / (0--3) = 15/3 = 5</span>

Bethany says that 3x+6+x and 3(x+2) and equivalent expressions. She used substitution to support her answer. Explain what Bethan

Vinvika [58]

She forgot about the final x at the end, because the first expression is 3x+6+x, and the second one is 3(x+2). The second one expands to 3x+6, but it doesn't have the final term at the end.

Also, 3 is not really a factor of x (technically it could be because x in unknown, but in terms of like terms and stuff it isn't) so you can't take a 3 out of x (unless you leave it as 1/3x I guess).

Anyway, yeah she forgot about the final x and therefore the factor she took out is incorrect anyway. She also could've simplified the first expression so that it became 4x + 6

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

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