Answer:
true -6 is greater than -7
Step-by-step explanation:
Length of circumference is 2πr
2 π r and r is equal to 2 cm
I.e 12.5 cm
The ordered pair (-1,5) is a solution to the system because it makes both equations true.
1) x+y=4
2) x-y=-6
1) -1 + 5 = 4
5-1 = 4 you can switch the order to make it easier to understand
so
4 = 4
2) -1 - 5 = -6
-1 + -5 = -6 you can change the sign in the middle and make y -
so
-6 = -6
The area of the shaded sector is one-fourth of the area of the whole circle so:

area of shaded region

The area of the shaded region is 9pi units^2
Oh it helps because a zero could count as a number when you write it down but it doesn't seem that way when u say it
