Answer:

Step-by-step explanation
The standard equation of a circle centered at origin is 
r = radius of the circle
The circle is passing through the point (0,5)
∴ radius 



∴ The equation of the circle is

Answer:
y = -6
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
0.75y−1.5y+0.5=5
0.75y+−1.5y+0.5=5
(0.75y+−1.5y)+(0.5)=5(Combine Like Terms)
−0.75y+0.5=5
−0.75y+0.5=5
Step 2: Subtract 0.5 from both sides.
−0.75y+0.5−0.5=5−0.5
−0.75y=4.5
Step 3: Divide both sides by -0.75.
Hope this helps!

Answer:
g(n) = 
Step-by-step explanation:
Given
3m - 5n = 11
Rearrange making m the subject
Add 5n to both sides
3m = 11 + 5n ( divide both sides by 3 )
m =
, thus
m = g(n) =
