Help help help please :)
1 answer:
-5 ≤ 1 - 2x < 9
Let's first break this down into two different inequalities.
1 - 2x ≥ -5
Subtract 1 from both sides.
-2x ≥ -6
Divide both sides by -2
x ≤ 3
Now, let's do the second inequality.
1 - 2x < 9
Subtract 1 from both sides.
-2x < 8
Divide both sides by -2
x > 4
let's combine each inequality to get our reduced compound inequality.
-4 < x ≤ 3
To plot this, put a hollow point at -4. A hollow point looks something like the letter o.
And put the second point at 3. This time, fill in the point so it looks whole.
Now, connect your points.
It should look something like this:

Answer:
B
Step-by-step explanation:
Since the triangle is right use Pythagoras' identity to solve for BC
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
BC² = AB² + AC² ← substitute values
BC² = 18² + 80² = 324 + 6400 = 6724 ( take the square root of both sides )
BC = = 82 → B
Answer:
A closed circle on 12, going to the left.
Step-by-step explanation:
h − 9 ≤ 3
+ 9 + 9
h ≤ 12
Look for a closed circle on 12, going to the left.
Hope that helps!
