I really dont know but if I did I would say I'm a 6 grader
Answer:
48 divided by 16
Step-by-step explanation:
16 oz=1 lb
Divided by 16 because there are 16 oz per pound
Given:
The point is (-5,7).
To find:
The image of the given point after 90 degrees counter clockwise rotation.
Solution:
If a point rotated 90 degrees counter clockwise, then
Let the given point is P(-5,7). Using the above rule, we get
Therefore, the image of the given point after 90 degrees counter clockwise rotation is (-7,-5).
Explanation:
first find the slope m of the line passing through the
the 2 given points
to calculate the slope m use the
