To solve an absolute inequality first step is to isolate absolute value expression.
Hence remove -4 from the left side. So, add 4 to each sides of the inequality.
2|x + 7|−4 ≥ 0
2|x + 7|−4 +4≥ 0 +4
2|x + 7| ≥ 4 Combine the like terms.
Divide each sides by 2.
|x + 7| ≥2
Next step is to remove the absolute value sign. So,
x + 7≥2 and x+7≤-2.
x≥2-7 and x≤-2-7
x≥-5 and x≤-9
So, the correct choice is C. {x | x ≤ -9 or x ≥ -5}.
Answer:
So the superhero covers 2450 miles in 30 minutes or 1/2 hour
Thus, he/she will cover (2450 x 2) miles in 1 hour
Therefore the answer is his/her velocity is (2450 x 2) miles/hour = 4900 miles/hour.
Hope this helps!

Hi there,
The answer is 1/3 cup per teaspoon. Here’s how...
All you have to do is divided 2/3 by 2.
We have to put a 1 under the 2 to at least represent it as a fraction.
2/3 / 2/1
Next we flip 2/1 into 1/2.
2/3 / 1/2
Now we are going to multiply.
2x1=2
3x2=6
We get 2/6, simplifying that we get 1/3 cup per teaspoon.
