Answer:
x=-4 and y=10
Step-by-step explanation:
Use the second equation to make y=x+6
sub y=x+6 into the first equation
-x-2*(x+6)=0
-x-2x-12=0
-3x-12=0
3x=-12
x=-4
Now sub x=-4 into the second equation
-(-4)+y=6
y=6+4
y=10
Answer:
no
Step-by-step explanation:
If you are talking 10 to the power of three then 54 is bigger. (:
In order to solve this problem, the primary equation to be used in this problem is the formula of the area of the circle which is A = pi r^2 where pi is a constant and r is the radius of the circle. The standard form of a circle is (x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center of the circle and r is the radius of the circle. In this case,
1) first circle
x^2 + y^2 = 36
that is (h,k) is at (0,0) and r = 6
2) second circle
<span>(x-1)^2+(y-2)^2=4
</span>that is (h,k) is at (1,2) and r =2
The area of the first circle is A1 = pi *6^2 = 36pi while A2 = pi* 2^2 = 4 pi
The difference of the two is equal to 32 pi or equal specifically to 100.48 units^2
