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.

Combine like terms.<br> - 2x - 14 = -3.- 1

UNO [17]

Answer:

combine -3-1

$- 2x - 14 = - 4$

if you want to solve for x then you would move the -14 to the left buy adding 14 to both sides.

$- 2x - 14 = - 4 \\ \: \: \: \: \: \: \: \: \: \: \: + 14 \: \: + 14$

your equation there will be

$- 2x = 10$

then you will divide -2 on both sides

$\frac{ - 2x}{ - 2} = \frac{10}{ - 2}$

finally x will equal

$x = - 5$
