Plot the points A(9, 11) and B(–3, –5). Find midpoint M of AB. Then show that AM = MB and AM + MB =AB

Alex_Xolod [135]

Answer:

The midpoint is (3, 3).

Step-by-step explanation:

We are given the two points A(9, 11) and B(-3, -5).

The midpoint is given by:

$\displaystyle M=\Big(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\Big)$

So:

$\displaystyle M = \Big( \frac{9+(-3) }{2}, \frac{ 11+(-5) }{2} \Big) = (3,3)$

The midpoint is (3, 3).

We want to show that AM = MB.

We can use the distance formula:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2$

The distance between A(9, 11) and M(3, 3) will then be:

$AM=\sqrt{(9-3)^2+(11-3)^2}=\sqrt{6^2+8^2}=\sqrt{100}=10$

And the distance between B(-3, -5) and M(3, 3) will be:

$MB = \sqrt{ (3-(-3))^2 + (3-(-5))^2 } = \sqrt{(6)^2+(8)^2} = \sqrt{ 100 } = 10$

So, AM = MB = 10.

Since AM = MB = 10, AM + MB = 10 + 10 = 20.

So, we want to prove that AB = 20.

By the distance formula:

$AB=\sqrt{(9-(-3))^2+(11-(-5))^2}=\sqrt{12^2+16^2}}=\sqrt{400}=20\stackrel{\checkmark}{=}20$

I am having trouble getting started with this question.

Answer:

A= 27/8 feet

B= 21/4 feet

Step-by-step explanation:

First, on both we need to convert to common denominators:

A.

Multiply:

4 1/4 times 2= 4 2/8

now we have to make 4 2/8 an improper fraction:

4 times 8=32, 32+2=34

34/8

Subtract the below ground length from the total length:

34/8-7/8= 27/8

Repeat:

B.

Multiply:

1 1/2 times 2= 1 2/4

Now we have to make 1 2/4 and 6 3/4 improper fractions:

1 times 4=4+2=6

6/4

6 times 4-24+3=27

27/4

Subtract the below ground length from the total length:

27/4-6/4= 21/4

i hope this helps u pls give a brainliest and a thx ;)
