Math Problem Statement

7k + 1 <= 8 or -7 < - 10

Solution

To solve the compound inequality 7k+187k + 1 \leq 8 or 7<10-7 < -10, we need to analyze each part of the inequality separately.

1. Solving 7k+187k + 1 \leq 8:

7k+187k + 1 \leq 8 Subtract 1 from both sides: 7k77k \leq 7 Divide both sides by 7: k1k \leq 1

2. Analyzing 7<10-7 < -10:

This inequality states 7-7 is less than 10-10. However, 7-7 is greater than 10-10, so this inequality is false.

Conclusion:

Since the second part 7<10-7 < -10 is false, the solution relies solely on the first part of the inequality. The final solution is: k1k \leq 1
