Answer:

(2, 3), (-3, 2), (-2, -3), (3, -2)

Step-by-step explanation:

You can pick any point you like, then rotate it around the origin to the four quadrants (or axes) by the transformation ...

(x, y) ⇒ (-y, x) . . . . . . . . . 90° rotation CCW

That is a rotation 90° CCW. Of course a rotation CW can do the same thing for you.

One possible square is ...

(2, 3), (-3, 2), (-2, -3), (3, -2)

6 out of 10 students completed their homework. What is the ratio of students who did not do their homework to those who did?

ludmilkaskok [199]

Answer:

2/3 or 2:3

Step-by-step explanation:

If 6 out of 10 students completed the homework then 4 out of 10 students did not complete the homework.

So the answer is 4/6 but we are not done yet.

The 4 comes from people who didn't do it and the 6 comes from people who did.

Since its asking the ratio of students who did not do their homework to those who did the 4 comes first.

As I said we are not done yet since we have to simplify.

4/6=2/3

So the answer is 2/3 or 2:3

A/50 = 3/5 Solve for “a” by cross multiplying then divide.

garik1379 [7]

Answer:

a = 30

Step-by-step explanation:

a/ 50 = 3/5

Using cross products

a*5 = 50 *3

5a = 150

Divide each side by 5

5a/5 = 150/5

a = 30
