1. Is the line that passes through the points A(0,1) and B(2,5) parallel to the line that passes through the points C(0,7) and D

kifflom [539]

You are correct that the slope of line AB is 2. To find the slope of the line CD, we can apply the slope formula again (like I assume you did with AB).

$m=\frac{15-7}{4-0}=\boxed{2}$

Therefore, since the slopes of lines AB and CD are equal, they are <u>parallel</u>

The list price for a window is $220. Net price is $160. What is the trade discount rate?

Artist 52 [7]

220-220r=160
Solve for r to get the discount rate
r=0.2727
r=0.2727×100
r=27.27%

Check
220−220×0.2727
=160

Which of the following is not rational

natulia [17]

Option A.

Step-by-step explanation:

Rational numbers -

Numbers that can be written as fraction of two whole numbers.
They can be positive, negative or zero.
They are numbers that can be written as fractions.
So, options B and C are examples of rational numbers.

Vinculum or Bar numbers -

These numbers are repeating decimals.
They are written with a line or a bar on top of the repeating numbers.
Bar numbers are irrational numbers.
So, option A is not a rational number.
