Answer:
(7, 19)
Step-by-step explanation:
We know that we are talking about circle C, which means that the center is point C. Since the diameter is AB, that means that AB goes through the center C and that center C is the midpoint of the segment AB.
Say the coordinates of B are (x, y). We can use the Midpoint Theorem to figure out B. The Midpoint Theorem states that for two points 
and 
, the coordinates of the midpoint are: 
.
Here, our two points are A(5, 1) and B(x, y). Then, the midpoint is: 
. We already know the midpoint is C(6, 10), so we can just set 6 equal to 
and set 10 equal to 
:
6 = ⇒ 12 = 5 + x ⇒ x = 12 - 5 = 7
AND
10 = ⇒ 20 = 1 + y ⇒ y = 20 - 1 = 19
So, the coordinates of B is: (7, 19).
Hope this helps!
Answer: 0
Step-by-step explanation:
(+1)+(-1)
Recall that the rule of BODMAS applies, also minus sign multiplied by the plus sign gives a minus sign
Thus, we have (+1-1)
Rewrite as (1-1) =0
Thus, the expression (+1)+(-1) equal Zero
Answer:
15 students in each bus.
Step-by-step explanation:
Subtract 10 from 100 and you get 90 then divide 90 by 6 and that gives you how many students in each bus
That is the simplest for the number can be in
Answer:
56 and 43
Step-by-step explanation:
(x+13)+x = 99
2x+13 = 99
2x = 99-13
2x = 86
x = 86/2
x = 43
Smaller number = 43
Larger number is 56
Check
56-43 = 13
56+43 = 99
