Answer:
Step-by-step explanation:
x + 7 ≤ -9 subtract 7 from both sides
x≤-16 this is your answer
If you're plotting it will be (-∞,-16]
Add 4 Subtract 1 Add 3
hope it helps
X ≈ √17
The number on the number line is roughly 4.1, and if you square 4.1, then you get 16.81, which 17 is the closest to.
x+(-2) >3
open the bracket
x-2>3
collect the like terms by taking 2 to the other side
x>3+2
x>6
