Answer:
domain(-4,6) and range(-1, 8)
Step-by-step explanation:
domain is an imput on x axis, and range on y
The area of a right triangle with side lengths 7 and 7 is 
Answer:A number decreased by 40
Step-by-step explanation: I really don't feel like explaining this lol...
The slope of the given line is found from the coefficient of x after dividing the equation by 2.
.. y = -3x +4
The given line has slope -3.
A perpendicular line will have a slope that is the negative reciprocal of this:
.. -1/(-3) = 1/3
This corresponds to your 3rd choice.
Answer:

Step-by-step explanation:
From the question we are told that
The vector given is

Also 
Generally

Here
is the magnitude of a which is mathematically represented as

=> 
b is vector which we will assume to have the following parameters

So

=> 
=> 
Hence the vector be can be mathematically represented as

This means that the vector b is more than one value since it is made up of variable
This means that if

Then
