Answer:
1. (4,6)
2. (-1, 8)
3. Not enough information given.
Step-by-step explanation:
1. Reflecting the point over the y-axis will place the point (-4,6) 4 units on the other side of the axis. This would place it at (4,6) without changing the y-coordinate.
2. Reflections across the line y=x means y and x trade places. This will result in the point (8,-1) becoming (-1,8).
3. Not enough information about the shape is given. Need to know where it is now to know where it will go.
Answer:
Step-by-step explanation:
These are logically difficult, so it makes sense to me you're asking about this.
so A = 1/2 (big arc - small arc)
and 360 = big arc + small arc
then
360 - small arc = big arc
so rewrite the top equation
A = 1/2(360-small arc -small arc)
63 = 1/2( 360 - 2 small arc)
2* 63 = 360 - 2 small arc
126 = 360 - 2 small arc
2 small arc = 360-126
2small arc = 234
small arc = 234/2
small arc = 117
x = 117°
If you have two negatives they cancel each other out and make a positive. The same if you have to positives the product will be positive. If you have a negative and a positive you multiply the numbers and bring down the negative. Same if you have a positive and a negative. Only two negatives cancel each other out, same with positives. For example -4(-5)(-1) you would use order of operations, 4 and the 5 cancel each other out and you multiply 20 by -1 which is -20 since you bring down the negative.
Answer:
I think the answer is D.
Step-by-step explanation:
Five plus two times a number means 5 + 2n vice versa.
