What would be the coordinates at 315° if the coordinates at 135° are at (-square root 2/2, square root 2/2)?

Answers

Answer 1

Answer:

Answer:

We choose C

Step-by-step explanation:

the coordinates at 135° are at ( $(-√(2) )/(2)$ , $(√(2) )/(2)$ )

As we can see, the x coordinate of the point is negative and the y coordinate of it is positive.

So this point is located at the quadrant ii

From 135 ° to 315°, it is rotated 180°

=> Each coordinate (x,y) is changed to (-x,-y)

= ( $(√(2) )/(2)$ , $-(√(2) )/(2)$ ) the new coordinate is located in quadrant iii

We choose C

Answer:

Answer in explanation

Step-by-step explanation:

We can use a number line to explain this subtraction.

The first thing to do is to locate the number 7 on the number line. This should be located to the right of the number line.

Then, since we are subtracting, we need to count left from the position of interest. So we will count 12 integers to the left of 7.

If things are right, we would land at -5

If it was a case of addition, we will need to keep counting right from the position of origin
