Add angles I guess but math
Answer:
Step-by-step explanation:
y= 2x+4.
-x- 5y=2x+4
-2x+y=4
-3x-5y
Answer:
8.2
Step-by-step explanation:
-7.2 to -7.2 is 0
-9.3 to -1.1 is 8.2
Pythagorean theorem is a^2+b^2=c^2
0^2=0
8.2^2=67.24
0+67.24=0
√67.24=8.2
The distance between the to points is 8.2
Answer:
a) The center coordinates O is (0,0)
b) The radius C = 15
Step-by-step explanation:
The given equation of the circle is : 
Now, general form of the equation of the circle is:

where (h,k) are the center co -ordinates and r is the radius of the circle.
Comparing the general equation with the given equation, we get

So, here the center coordinates (h,k) = (0,0)
And the radius of the given circle is r = 15
