Answer:
centre = (1, - 3 )
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x - 1)² + (y + 3)² = 73 ← is in standard form
with (h, k ) = (1, - 3 ) ← centre

Answer:
c.28
Step-by-step explanation:
Given
f(x) = 8x + 10 and g(x) = 6x - 4
f(4) = 8*4 + 10
= 32 + 10
= 42
g(3) = 6 * 3 - 4
= 18 - 4
= 14
Now
f(4) - g(3)
= 42 - 14
=28
hope it will help :)
