Answer:
1. x>-7
2. x>-21
3. xlessthanorequalto-21
4. xlessthanorequalto16
Explanation:
1. To solve for the value of x we just need to divide by -5. When we divide or multiply by a negative number the inequality sign will flip. This means that instead of being less than, it will become a greater than sign. Since dividing 35 by -5 will result in -7 we can say that the answer to question 1 is x>-7
2. In this scenario we would not flip the sign because we are not dividing by a negative number, since 2 is not a negative. Dividing -42 by 2 we can come up with x>-21
3. Like in the last scenario we won't flip the sign and only need to multiply -7 by 3, meaning that we will get xlessthanorequalto-21
4. Like in the first scenario we will need to flip the sign because we are multiplying by a negative number, meaning that we will multiply -4 by -4, so xislessthanorequalto14
Hope this makes sense!
