The points (a,5) and (9,b) are on the circle x^2+ y^2= 125.
1 answer:
Answer:
a = 10
b = 6.633
Step-by-step explanation:
x²+ y²= 125.
In this equation, the value of x and y represent the coordinates of x and y respectively of point on which the circle passes.
<u>(a,5)</u>
x²+ y²= 125
a² + 5² = 125
a² + 25 = 125
a² = 125-25
a² = 100
a = √100 = 10
(9,b)
x²+ y²= 125
9² + b² = 125
b² 125 - 81
b² = 44
b = √44 = 6.633

Answer:
infinite solutions
Step-by-step explanation:
4x=4x
Divide each side by x
4x/x = 4x/x
4 =4
This is always true,no matter what value we put in for x. So there are infinitely many solutions to the equation.
