X= your age
400-2x=244
-2x=-156
x=78
you are 78 years old
2x^-2y^-2 = 2/x^2y^2 = 2/(2)^2 x (3)2 = 2/4 x 9 = 2/36 = 1/18
The answer is C, you can solve this by sin(30)= 8/c since sine is opposite over hypotenuse and since c equals 16 there is only one possible solution
Answer:
The name given to the shaded region would be the positive interval because all f(x) values in that region are positive.
