(x^2 - 3x + 1) - (x^2 + 2x + 7)
Distribute the negative
x^2 - 3x + 1 - x^2 - 2x - 7
Combine like terms
-5x - 6
Horizontal line is y=a, where a is a constant (number).
We need to choose equation this type.
y= - 7, means that for all values of x y=7.
So, answer is
B. y= - 7
You should look for outliers. If there is an outlier then you should use median because if you use mean the data would be skewed.
Answer:
x-intercepts: (1,0), (2,0), (5,0)
y-intercepts: (0,-10)
Step-by-step explanation:
One factor of the function
is 
Factor the polynomial in the following way:

Now factor the quadratic in brackets:

Hence,

The x-intercepts are points at which y = 0, so

The y-intercepts are points at which x = 0, so

Answer: 20 miles? lol
