Find the coordinates of the midpoint of the segment given the endpoints p( -3,-7) and q (3, -5)

Answers

Answer:

(0,-6)

Step-by-step explanation:

The midpoint from -3 to 3 is 0, so the first coordinate is 0

The midpoint from -7 to -5 is -6, so the second coordinate is -6

Answers

Here are my answers to the given questions above:
Part 1. Here is my example of a real life scenario that describes what is happening. Let us say, I have 2 cookies and the bottle of milk costs 11 dollars, and 3 cookies and 4 bottles of milk cost 24 dollars.
Part 2.
y=11-2x
3x+4(11-2x)=24
3x+44-8x=24
-5x=-20
x=4
y=11-8
y=3
Therefore, each cookie costs 4 dollars, and a bottle of milk costs 3 dollars.
Hope this answer helps. Let me know if you need more help next time.

FIND X AND Y PLEASEEE

Answers

Answer:

y = 2

x = -3.5

Step-by-step explanation:

3y and (2x + 13) are same-side angles.

that means they are equal

(that's not the real term for it, I just forgot what it's called)

using that, you can make this equation:

3y = 2x + 13

3y - 13 = 2x

(3y - 13)/2 = x

(5y - 4) and 3y are vertical angles.

vertical angles are equal.

using this, you can make the following equation:

5y - 4 = 3y

5y - 3y - 4 = 0

5y - 3y = 4

2y = 4

y = 2

now, substitute y for 2 in the original equation.

(3y - 13)/2 = x

(6 - 13)/2 = x

-7/2 = x

-3.5 = x

What values of x make the equation x^2 + 9x – 22 = 0 true? Check all that apply.–11

Answers

If you would like to solve the equation x^2 + 9x - 22 = 0, you can do this using the following steps:

x^2 + 9x - 22 = 0
(x - 2) * (x + 11) = 0
1. x = 2
2. x = - 11

The correct result would be x = 2 and x = - 11.

Answer:

x = 2 , - 11.

Step-by-step explanation:

Given : x² + 9x – 22 = 0

To find : What values of x make the equation.

Solution : we have given x² + 9x – 22 = 0

On factoring

x² + 11x - 2x – 22 = 0 .

Taking common x from first two term and -2 from last two terms.

x ( x +11) - 2 (x +11) = 0.

On grouping

(x -2) (x +11) = 0
