For which inequality would x = 8 not be a solution?4x + 3 > 09x - 5 < 100x + 4 ≤ 1072 ÷ x ≥ 4
galina1969 [7]

Given:

Given the inequalities:4

\begin{gathered} 4x+3>0 \\ 9x-5

Required: Identify the inequality in which x = 8 is a solution.

Explanation:

Substitute 8 for x in each inequality and check whether it satisfies the inequality.

Consider 4x + 3 > 0.

4\cdot8+3=35>0

So, x = 8 satisfies the inequality 4x + 3 > 0.

Consider 9x - 5 < 100.

9\cdot8-5=67

So, x = 8 satisfies the inequality 9x - 5 < 100.

Consider x + 4 ≤ 10.

8+4=12>10

So, x = 8 not satisfies the inequality.

Consider 72 ÷ x ≥ 4.

72\div8=9\ge4

So, x = 8 satisfies the inequality.

Final Answer: The inequality in which x = 8 is not a solution is x + 4 ≤ 10.

What happens to energy during a change of state? Why is it a physical change?​
Flura [38]

Answer & Explanation:

Energy is heat. For example, if you boil a cup of water it has more energy than   a cup at room temperature. It is considered a physical change because its properties do not change only the state of matter. On the other hand, if wood burns then that is a chemical change because it changes its chemical properties. Please rank as Brainliest if this helps! Thank you!
