Part A
The given line passes through (-2,2) and it is parallel to the line
We need to determine the slope of this line by writing it in slope -intercept form.
The slope of this line is
The line parallel to this line also has slope
The equation is
We substitute (-2,2)
The required equation is
PART B
The given line is
The slope of this line is
The slope of the line perpendicular to it is
The equation of the line is
We substitute the point, (-2,2)
The equation of the perpendicular line is
Answer:
Step-by-step explanation:
-4 = 5 + f....we want to isolate f, so subtract 5 from both sides
-4 - 5 = 5 - 5 + f
-9 = f <===
Answer:
C
Step-by-step explanation:
When completing the square, we essentially want to create a perfect square trinomial by adding a constant.
If we have the following expression:
And we want to complete the square, we will need to divide the b-coefficient by half and then square it.
Thus, the added term should be:
In the given equation, we have:
The b term here is 8. Therefore:
The value we would add would be 16.
The answer is C.
Further notes:
To complete the square, add 16 like mentioned earlier. However, we also need to subtract 16 to balance things out:
The expression inside the parentheses is now a perfect square trinomial. Factor it:
And we are done!
Step-by-step explanation:
you need to find the area and add them together
The closest would be 7
7x7 is 49 and that is the closest
