- Find the coordinates of A if B(0,5.5) is the midpoint of AC and C has coordinates<br><br> (-3,6).
emmainna [20.7K]

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:

Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)

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

B=\left(\dfrac{a+(-3)}{2},\dfrac{b+6}{2}\right)

(0,5.5)=\left(\dfrac{a-3}{2},\dfrac{b+6}{2}\right)

On comparing both sides, we get

\dfrac{a-3}{2}=0

a-3=0

a=3

and,

\dfrac{b+6}{2}=5.5

b+6=11

b=11-6

b=5

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

7x5x3 = 105

1. Just multiply them together.

28 - 3(2+4)/9 = 26

1. PEMDAS

2. Add inside the parenthesis: 28 - 3 x 6 / 9

3. Multiply: 28 - 18 / 9

4. Divide: 28 - 2
