Answer 1

Ответ:

$a)x \leqslant 8 \\ b)y \geqslant 0 \\ c)5 < a \leqslant 7 \\ d) - 2 \leqslant b < 1$

Answer 2

Solution:

To solve the given inequalities, let's analyze each one separately:

a) x ≤ 8

b) u ≥ 0

c) a > 5 and a ≤ 7

d) b > -2 and b < 1

Let's break down each inequality and find the solutions:

a) x ≤ 8

The inequality states that x is less than or equal to 8. This means that any value of x that is less than or equal to 8 satisfies this inequality. The solution set for this inequality is x ≤ 8.

b) u ≥ 0

The inequality states that u is greater than or equal to 0. This means that any value of u that is greater than or equal to 0 satisfies this inequality. The solution set for this inequality is u ≥ 0.

c) a > 5 and a ≤ 7

The inequality states that a is greater than 5 and less than or equal to 7. This means that any value of a that is greater than 5 and less than or equal to 7 satisfies this inequality. The solution set for this inequality is 5 < a ≤ 7.

d) b > -2 and b < 1

The inequality states that b is greater than -2 and less than 1. This means that any value of b that is greater than -2 and less than 1 satisfies this inequality. The solution set for this inequality is -2 < b < 1.

Therefore, the solutions to the given inequalities are:

a) x ≤ 8

b) u ≥ 0

c) 5 < a ≤ 7

d) -2 < b < 1

I hope this helps! Let me know if you have any further questions.
