Question

Неравенства a)x <2;7. б)х_<8в)х <4 4/5

Answer 1

Если подобрать х:
1)х={2,6 и все числа меньшие этого сисла }
2)х={8,7,6,5...}
3)х={4,7;4,6;4,5...}

Answer 2

To solve each inequality, let's find the value of "x" that satisfies the given conditions.

a) x < 2:

For this inequality, any value of "x" that is less than 2 would satisfy it. It forms an open interval on the number line. For example, x = 1 or x = 1.5 would satisfy this inequality.

b) x ≤ 8:

This inequality represents a closed interval, where "x" can be equal to 8. Any value of "x" that is less than or equal to 8 would satisfy the inequality. For example, x = 8, x = 7, or x = -3 would satisfy this inequality.

c) x < 4 4/5:

To solve this inequality, we first need to convert 4 4/5 to an improper fraction:

4 4/5 = (5 * 4 + 4) / 5 = 24 / 5

Now the inequality becomes:

x < 24/5

So any value of "x" that is less than 24/5 would satisfy this inequality. It forms an open interval on the number line. For example, x = 4, x = 2, or x = -1 would satisfy this inequality.
