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:
1 7/10
Step-by-step explanation:
After you minus the numbers you simplify them and get 1 and 7/10
Answer:
x=12 makes (X-12)/(x-8) equal to zero
x=8 makes (X-12)/(x-8) undefined
Step-by-step explanation:
(x-12)/(x-8) = 0
The first step is to multiply each side by x-8
(x-8) *(x-12)/(x-8) = 0 * (x-8)
This cancels the denominator. x≠ 8 because the denominator would equal 0 and then it becomes undefined.
x-12 = 0
Add 12 to each side
x-12+12 = 0+12
x = 12

Answer:
<h3>4x^2/3</h3>
Step-by-step explanation:
Given the expression (8x)^2/3
This can also be expressed as;
(8x)^2/3
= (2^3x)^2/3
= (2³)^2/3 * x^2/3
= 2^2 * x^2/3
= 4x^2/3
Hence the equivalent expression is 4x^2/3
