Given:
Coordinates of point C are (-3,6).
Point B(0,5.5) is the midpoint of AC.
To find:
The coordinates of A.
Solution:
Let the coordinates of point A are (a,b).
Formula for midpoint:

Using the above formula, the midpoint of A(a,b) and C(-3,6) is


On comparing both sides, we get



and,




Therefore, the coordinates of point A are (3,5).

Answer:
x = 4, y = 1
(4, 1)
Step-by-step explanation:
-2x - y = -9
5x -2y = 18
-2x - y = -9
+2x +2x
-y = 2x - 9
/-1 /-1
y = -2x + 9
5x -2y = 18
5x - 2(-2x + 9) = 18
5x + 4x - 18 = 18
9x - 18 = 18
+ 18 + 18
9x = 36
/9 /9
x = 4
Now, we solve for y:
-2(4) - y = -9
-8 - y = -9
+ 8 +8
-y = -1
/-1 /-1
y = 1
(x, y) -> (4, 1)

The legs of an isosceles triangle are 7cm longer than the base. Find the legs if the perimeter of the triangle is 38cm.
(38 - 7 - 7) : 3 = <em>8 cm (base)</em>
8 + 7 =
<h2><u><em>
15 cm ( Legs)</em></u></h2>
check
8 + 15 + 15 = 38
the answer is good
