Answer:
Step-by-step explanation:
The area of a sector with measure 
in degrees is given by 
, where 
is the radius of the sector.
What we're given:
Solving, we get:
*Notes:
- units should be in square meters (area)
- the problem does not say whether to round or leave answers in term of pi, so you may need to adjust the answer depending on what your teacher specifically wants
I literally need this too and i have no idea
First, you want all the variables to be on one side:
a - 3b = 4
a - b = -2
Now you want to eliminate one of the variables, in this case a is easiest.
Subtract the second equation from the first and you're left with:
-2b = 6
so b = -3
Sub the value of b back into either of the equations and solve for x:
a - (-3) = -2
a = -5
So your answer is (-5,-3)
Answer:
A
Step-by-step explanation:
if the rule is (-x,y) then that just means the x changes
(3,-2) changes to (-3,-2)
