Answer:

k = 10

Step-by-step explanation:

∡ZYX = 180° - 115° = 65° (angles in a line add up to 180°)

*∡ <em>stands for </em><em>angle.</em>

<em />

∑ of  ∡Z , Y and X should be equal to 180° (angles in a triangle add up to 180°)

∴ (4k + 5)° + 65° + (6k + 10)° = 180°

10k + 80 = 180

10k = 100

k = 100 ÷ 10 = 10

A rotation maps point A to A’.
weeeeeb [17]

Answer:  The answer is (C) 180° rotation.

Step-by-step explanation:  Given that the point A maps to the point A' by a rotation. We are to select the statement that describes the rotation.

In the given figure, the co-ordinates of point A are (-3, 5) and after rotation, the co-ordinates of point A' are (3, -5).

Therefore, the point (x, y) changes to (-x, -y) after rotation. This is the result of 180° rotation.

Therefore, the point A is rotated through an angle of 180° to reach at the point A'.

Thus, the correct option is (C) 180° rotation.

1. The function of this graph is f(x) = 0.5x + -2 
Plug (-2) into the x variables so it looks like: 
f(-2) = 0.5 (-2) + -2
Then solve. 
Answer: f(-2) = -3 
**I'm not as sure about this one, so I might be wrong

2. 
For #8, the y-intercept is 4 (you're right) and it represents the initial distance before she started hiking (D)
