The link is up there ^^^

Answer 5

i just insert the equation and it answer it for me?

Answer 6

x-3<-9 you want to find x, so you need to get rid of the -3, so you add 3 to both sides x-3+3<-9+3 -3+3=0 and -9+3=-6 so x<-6 and then -12+5 on the other so you get x>/=7 So the answer is C.

Answer 7

idk how to work that

Answer 8

Thanks JoCel

Answer 9

Because its less than but not equal to 6 and greather than and equal to 7 so you shade in 7 and do all to the right and you don't shade in -6 and do everything to the left.

Answer 10

Henry's rocket is designed to launch to a height of 100 feet in the air. The measurements so far have the launch height (h) varying no more than 4 feet. Which inequality below represents this scenario? (5 points)


|h − 4| less than or equal to 100
|h + 4| greater than or equal to 100
|h − 100| less than or equal to 4
|h + 100| greater than or equal to 4

Answer 11

Isn't the answer C?

Answer 12

I mean D

Answer 13

No, C. is correct. |h - 100| represents the absolute value of the difference between the actual height and the predicted height of 100 feet.
This value varies no more than 4 feet, so |h - 100| <= 4
