Step-by-step explanation:
Answer:
D
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
Here (h, k) = ( - 
, 
) and r = 
, thus
(x - (- ))² + (y - )² = ( )², that is
(x + )² + (y - )² = 
→ D
Answer: -1
Step-by-step explanation:
(4*X-7) = (6X -5)
4X -7 = 6X - 5
2X = -2
X = -1
Answer:
Step-by-step explanation: x - 6
The given equation can be re-written as y = ---------
-3
Arbitrarily choose x = 0. Then:
x - 6 0-6
y = --------- = ----------- = 2, so (0, 2) is a point on the graph which is also the
-3 -3 y-intercept
Arbitrarily choose x = 6. Then y = 0, and (6, 0) is another point on the graph
which happens to be the x-intercept
arbitrarily choose x = 12. Then y = (12 - 6) / (-3) = -2. Then (12, -2) is
another point on the
graph.
Plot (12, -2), (6, 0) and (0, 2). Draw a line through these three points.
The
first choice gives you the same result. The factor of 5 can be removed to the outside of the summation symbol.
