Solve for x: −2x − 4 > 8 (2 points) Question 4 options: 1) x < −6 2) x > −6 3) x < −2 4) x > −2
1 answer:
Option 1: x<-6 is the right answer
Step-by-step explanation:
The inequalities are solved by isolating the variable on left side of the inequality.
Given
Adding 4 on both sides
Dividing by 2 on both sides
The variable should not be negative.
Multiplying both sides by -1
Hence,
Option 1: x<-6 is the right answer

Step-by-step explanation:
To do this, we will make use of the following rules:
Direct Variation: =>
Inverse Variation: ==>
Joint Variation: ==>
Direct, then inverse variation: ==>
Having highlighted the rules, the solution is as follows:
1. m varies directly to a
2. p varies inversely as q.
3. directly as s and inversely as t.
4. z varies jointly as
5. F varies directly as the
6. d varies jointly r and t
7. P is inversely proportional to h.
8. P varies directly as V
9. d varies directly as the square of t
10. s varies jointly as b and d and inversely as the square L
