Answer:
<h2>neither</h2>
Step-by-step explanation:
If AB an CD are parallel, then their slopes are the same.
If AB and CD are perpendicular, then the product of their slopes is equal -1.
The formula of a slope:

Calculate the both slope:


The line AB and line CD are not parallel

The line AB and line CD are not perpendicular.
Answer:
12 minutes
Step-by-step explanation:
(50miles/60 minutes)/5 = 10 miles/12 minutes
The first thing to do with these problems is to convert them into y=mx+b form; this will literally show you the answer to slope and y intercept since m=slope and b=y intercept.
To convert, isolate the y and the rest should fall into place. Subtract 2x from 4y and the other side of the equation to get the equation 4y= -2x+9 (put the x first because of mx+b). Then Divide the 4 from y and do the same to the other side to get y= -1/2x+9/4. M= -1/2 so that is the slope. B=9/4 so that is the y intercept
<span>Scientific notation is the way that scientists easily handle very large numbers or very small numbers. Scientific notation is written by writting a decimal number between 1 and 10 together with an exponent of 10.
Given

First, using distributive property of numbers, seperate the decimal numbers and the exponents of 10, we have

Because, scientific notation requires that the decimal number part be a number between 1 and 10, we move the decimal point 1 place foward and subtract 1 from the exponent of 10.
Therefore, </span><span>
