Determine the relationship between the two vecors
asambeis [7]

Answer:

Step-by-step explanation:

Since there exists a scalar  

λ

λ

(namely  

λ=a⋅b

λ=a⋅b

) such that  

b=λa

b=λa

, the directions of the two vertices are the same (they are collinear). This implies that  

|a⋅b|=|a||b|

|a⋅b|=|a||b|

.

So,  

|a|=|(a⋅b)b|=|a||b||b|

|a|=|(a⋅b)b|=|a||b||b|

which implies that  

|b|=1

|b|=1

Find the slope of a line perpendicular to <br><br> Y= -x -1
ad-work [718]
<h2>Greetings!</h2>

Answer:

The slope is 1.

Step-by-step explanation:

First, we must find the slope of the current equation.

This is the number in front of the x.

Seeing as this is -x, or -1x, the slope of this line is -1

When finding the slope of a line perpendicular, you need to find the \frac{-1}{slope}

So, in this case it is:

\frac{-1}{-1}

The minuses cancel out, leaving with 1 over 1 or 1/

So the slope of the line perpendicular is 1!


<h2>Hope this helps!</h2>

How can you solve for x and y?
galina1969 [7]

ah, those are systems you want one variable to cancel out. I would time the bottom equation by -1 so x cancels then u solve for y. then u plug all back in to solve for x.
