Answer:

f = 3

Step-by-step explanation:

Slope m = (y2-y1)/(x2-x1)

Using (6,8) and (f,-7) then

m = (-7 - 8)/(f - 6) = 5

- 15 = 5(f - 6)

-15 = 5f - 30

5f = 30 - 15

5f = 15

f = 3

Citrus2011 [14]

Answer:

1 = 128 degrees

2 = 52 degrees

3 = 47 degrees

4 = 133 degrees

5 = 81 degrees

Step-by-step explanation:

angle 2 and 52 degrees are corresponding angles so they are equal.

angle 3 and 47 degrees are corresponding angles so they are equal.

angles 1 and 2 are supplementary angles so their sum is 180 degrees.

angles 3 and 4 are supplementary angles so their sum is 180 degrees.

angle 5 = 180 - 52 - 47 = 81 degrees

Lines a and b are parallel.

Wittaler [7]

m and 125º are supplementary angles:

m + 125º = 180º

m = 180º – 125º

m = 55º <——— this is the answer.

I hope this helps. =)

Answer:

Step-by-step explanation:

-When the function moves to the right or left to the x axis, the number has to be in "( )"

-If it moves to the right, you SUBTRACT the amount of units

-It it moves to the left, you ADD the amount of units.

So in this case, it is moving to the right 12 units so it is $(x-12)^{2}$
