Answer:

Step-by-step explanation:






Answer:
(7, 0) and (-5, 0)
Step-by-step explanation:
<u>Vertex form</u>
(where (h, k) is the vertex)
Given:

Given:



Therefore:

The x-intercepts are when y = 0






Therefore, the x-intercepts are (7, 0) and (-5, 0)
Given:
The system of equation is


To find:
The solution of given system of equations.
Solution:
The slope intercept form of a line is

Where, m is slope and b is y-intercept.
Write the given equation in slope intercept form.
The first equation is


...(i)
Here, slope is
and y-intercept is 4.
The second equation is
...(i)
Here, slope is
and y-intercept is -4.
Since the slopes of both lines are same but the y-intercepts are different, therefore the given equations represent parallel lines.
Parallel lines never intersect each other. So, the given system of equation has no solution.
Hence, the correct option is B.
Answer:
5
Step-by-step explanation:
Hello There!
The mean is pretty much the average
So to find the mean we first add up all of the values
2+3+6+6+7+8+8=40
Then we count the amount of points
There are 8 points
our final step is to divide the total value by the total number of points
40/8=5
so the mean (average) would be 5
