Answer:
I thinks its r = 11
Step-by-step explanation:
So you just need to take the number to the r and multipliy it by r So,
9x2=18
then minus it by the other number which would Be 7 so.
18-7=11
3x + 2y = 2, -2x + y = 8
Let us just solve by testing each of the options.
Option A is (-2, 4), that is x =-2 and y = 4
check: for x = -2 and y = 4
3x + 2y = 2
3*-2 + 2*4
-6 + 8 = 2
2 = 2
So both sides are equal.
-2x + y = 8 x = -2 and y = 4
-2*-2 + 4
4 + 4
8
8 = 8
Since option A (-2, 4) satisfies both equation, no need to test other options.
Option A is the answer.
Answer:
Radius=4 units
Centre= (0,-10)
Step-by-step explanation:
Given equation of circle is x^2 +(y-10)^2=16
Comparing it with (x-h)^2 +(y-k)^2 = r^2 ,we get,
r=4
Since, centre of a circle=(h,k)=(0,-10)
