(r,theta) represents polar coordinate .
And in (r,theta), there is neither any restriction on r nor on theta. It means both r and theta can either be positive or negative .
For e.g. (2,30 degree), (2,-30 degree) both are correct .
So the given statement is true .
(4 - 5y) - 2(3.5y - 8)
first distribute
(4- 5y) - 7y + 16
Then simplify
-12y + 20
Then simplify
4(-3y + 5)
hope this helps
Answer:
2 1/8
Step-by-step explanation:
7/8 is the same as 0.875 and therefore you need 0.125 also known as 1/8 to make it a whole number. When you add it to the already existing whole 2 you get three. Subtract three from five to make two which is what you need to add on top to finally get 5.
A right angle is 90 degree, and all the three angles make a sum of 180, so the two acute angles will always add up to be 90
Answer:
He have to eat each piece in 
Step-by-step explanation:
Given:
Brian claims that he can eat a pie that is divided into six equal pieces In two minutes.
If he can eat the whole pie in two minutes.
Now, to find the time he have to eat for each piece.
So, to solve by using unitary method:
If Brian can eat 6 pieces in = 2 minutes.
Then, he can eat 1 piece in = 
Therefore, he have to eat each piece in
