Answer:
D.
Step-by-step explanation:
[7^(-8)]^(-4) =
A power raised to a power: multiply the exponents.
= 7^[(-8)*(4)]
= 7^(32)
Answer: D.
Given:
Given the inequalities:4

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.

So, x = 8 satisfies the inequality 4x + 3 > 0.
Consider 9x - 5 < 100.

So, x = 8 satisfies the inequality 9x - 5 < 100.
Consider x + 4 ≤ 10.

So, x = 8 not satisfies the inequality.
Consider 72 ÷ x ≥ 4.

So, x = 8 satisfies the inequality.
Final Answer: The inequality in which x = 8 is not a solution is x + 4 ≤ 10.
Answer:
Solve for

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!
