Answer:
2.025
Step-by-step explanation:
In this problem, you don't necessarily need to find the exact values of a and b. Rather, find the value of (a+b) first, and then you can substitute it into the next equation. First, you can divide both sides of the first equation 2(a+b)= -8.1 by 2, to get (a+b)=-4.05. Now, subsitute the value of (a+b) into the second equation, -0.5(a+b), to get -0.5(-4.05). From here, you can calculate that -0.5 times -4.05 is 2.025. Hope this helped!
18=3(x-1)
18=3x-3
18-3=3x
15=3x
15/3=x
x=5
Answer:
Step-by-step explanation:
Solution= V=0
we know that
the equation of the circle is of the form
where
(h,k) is the center of the circle
r is the radius of the circle
in this problem we have
so
the center is the point 
the radius is 
therefore
the answer is
The radius of the circle is equal to
