Can someone show me how to do this or like just do a single problem for me to show me how to do it I don’t understand how to do the work but I know the answer please I need help it’s due tommarow

Step-by-step explanation:

The coordinates of the midpoint are the average of the endpoints.

40. Endpoint (-8, 11), and midpoint (-6, 9).

-6 = (x + -8) / 2

-12 = x − 8

x = -4

9 = (y + 11) / 2

18 = y + 11

y = 7

The other endpoint is at (-4, 7).

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊

you are playing an adventure game on your computer. you come across a troll who won't let you pass and there is no other way to get to the other side of the river except over the bridge he is guarding.

the troll is a nerd. he takes great delight in watching people struggle with his problems. very few get them. he only gives you one chance and then he changes the puzzle. you have to solve this one.

before you are four blocks. they are numbered 11,6, -7,21.

he tells that the answer he wants is minus and between -1 and - 2. you can use +, -, ×, ÷   ( and ) as many times as you like or no times at all. you don't like the way he's looking at you, but you need to cross the bridge. what do you do?
