The true statement is the circle has the radius equal to 7.
<h3>What is Equation of circle?</h3>
The general equation for a circle is (x-h)² + (y-k)² = r², where ( h, k ) is the center and r is the radius.
As, standard form of equation of circle is
(x-h)² + (y-k)² = r²
At origin, equation of circle will be
(0-h)² + (0-k)² = r²
r² = x² + y²
Now, The line intersects the circle at (0,7)
r² = 0² + 7²
r² =49
r=7.
Hence, the circle has the radius equal to 7.

Answer:
7x -1 is correct after combining like terms
Step-by-step explanation:
6+8x-7-x
To simplify algebraic expression we combine like terms
In the given expression
-x or -1x are same
8x and -1x are like terms
6 and -7 are also like terms
8x-1x= 7x
6 - 7 = -1
So 7x -1 is correct after combining like terms
