What is the image of the point (3,-8) after a rotation of 90° counterclockwise about the origin?

1 answer:

6 0

Answer:
(8,3)
Step-by-step explanation:
When we rotate a point 90° counterclockwise around the origin, it's the same as rotating it 270° clockwise around the origin.
When we rotate something 270° clockwise around the origin, the original coordinates (x, y) becomes (-y, x).
y is -3, and -(-3) is just 3, since two negatives make a positive.
x just remains x, but it's in a different position.
This makes the new coordinate .
Hope this helped!

Which is the slope of the line that passes through the points (3,17)(3,17) and (7,25)(7,25)?

PilotLPTM [1.2K]

The slope is 2, because you subtract the points 3,17 from 7,25 to get 8/4/ Simplify that into 2.

Mia went for a long bike ride. She rode 10.25 kilometers each hour for 4.25 hours. How far did Mia travel on her bike ride?

Art [367]

Answer:

43.5625 kilometers

Step-by-step explanation:

hi!

To solve this problem, you have to take note of the important information which is:

- 10.25 km/hour

- 4.25 hours

- how far did she travel?

To answer the question, you need to take Mia's hourly rate (10.25 km PER hour) and multiply that by how many hours she rode her bike for (4.25) which equals 43.5625 kilometers

10.25*4.25 = 43.5625 kilometers

I hope this helped :)
