Answer:
(x - [-1])² + (y - [-1])² = [13]
Step-by-step explanation:
If P and Q are the end-points of the diameter PQ, midpoint of the segment PQ will be the center of the circle. (Definition of the center of a circle)
Midpoint of a segment having extreme ends and
Coordinates of the center =
Since, extreme ends of the diameter are P(-4, -3) and Q(2, 1)
Center of the circle =
= (-1, -1)
Radius of the circle = Distance between the center and Q,
Since distance between the two points and is,
d =
Radius of the circle =
=
=
Equation of the circle will be,
(x - h)² + (y - k)² = r²
Where (h, k) is the center and 'r' is the radius of the circle,
(x - [-1])² + (y - [-1])² = [13]
Answer:
<h2>
Larger number = 10</h2><h2>
Smaller number = 5</h2>
Step-by-step explanation:
Let larger number be x
Let smaller number be y
---> equation (i)
-----> equation (ii)
Equate equation (i) and (ii),
Move variable to L.H.S and change its sign:
Similarly, Move constant to R.H.S and change its sign
The difference sign (-) will be cancelled on both sides
Putting the value of y in equation (ii) in order to find the value of X ( larger number)
Plug the value of y
Calculate the product
Hence,
Smaller number = 5
Larger number = 10
Hope this helps..
Best regards!!
Kay = x
Mary is twice as old as Kay
⇒ Mary = 2x
Jane is 3 years older than Mary
⇒ Jane = 2x + 3
Answer: 2x + 3
Answer:
the answer is B. the sum will be close to ½
½= 14/28
1/4 + 2/7
= (7+8)/28
= 15/28
so, the answer is B
Step-by-step explanation:
hope it helps you
