Answer:

y=-3x+5

Step-by-step explanation:

y=-3x-7

slope is -3

parallel lines have the same steepness, they have the same slope.  The slopes are equal.

y-y1=m(x-x1)

y-2=-3(x-1)

y-2=-3x+3

y=-3x+3+2

y=-3x+5

<h3>Answer:    0.157</h3>

========================================================

Explanation:

Convert the fraction 9/50 to decimal form. You can use either long division or a calculator.

You should find that 9/50 = 0.18 which is the same as 0.180

So the original compound inequality is the same as saying 0.125 < x < 0.180

This tells us that x is between 0.125 and 0.180 where x is not equal to either endpoint. We simply need to pick anything in this interval. It can be anything you want (I recommend to use a number line to help pick a value). One such value is 0.157. There are infinitely many values you can select from.

The number 0.157 is between 0.125 and 0.180, ie  0.125 < 0.157 < 0.180

It's very similar to saying 157 is between 125 and 180, ie 125 < 157 < 180.

Zielflug [23.3K]

Answer:

$85,734

Step-by-step explanation:

We have been given that Karel sells goods to customers in exchange for a $100,000 non-interest-bearing note due in 2 years. The interest rate on this type of loan is 8%. We are asked to find the present value of the note.

PV=FV\frac{1}{(1+r)^n}, where,

PV = Present Value,

FV = Future Value,

r = Interest rate in decimal form,

n = Time

Let us convert given interest rate into decimal form as:

8\%=\frac{8}{100}=0.08

PV=100,000*\frac{1}{(1+0.08)^2}

PV=\frac{100,000}{(1.08)^2}

PV=\frac{100,000}{1.1664}

PV=85733.882030

PV\approx 85,734

Therefore, the present value of the note is $85,734.
