<h2>Answer:</h2>

This is a 2-step equation. We will solve it in 2 steps.

$-2x + 1 = -6\\\\-2x = -7\\\\x = \frac{7}{2}$

The solution for this equation is x =<em> </em> $\frac{7}{2}$ .

Choose the correct simplification of the expression (-9a^3b^2c^10)^0

Flauer [41]

Option C: 1 is the simplification of the expression $\left(-9 a^{3} b^{2} c^{10}\right)^{0}$

Explanation:

The given expression is $\left(-9 a^{3} b^{2} c^{10}\right)^{0}$

We need to simplify the given expression.

<u>Simplification:</u>

To simplify the given expression, let us apply the exponent rule, $a^{0}=1$ where $a \neq 0$

Thus, the the exponent rule $a^{0}=1$ means that any value (except zero) to the power of zero is equal to one.

Thus, the expression $\left(-9 a^{3} b^{2} c^{10}\right)^{0}$ becomes,

$\left(-9 a^{3} b^{2} c^{10}\right)^{0}=1$

Therefore, the simplified expression is 1

Hence, Option C is the correct answer.

What can be said of the result if a negative is raised to an odd power?

mel-nik [20]

Let's say we have the base -2 and we raise it to the third power, what will happen?

Well, $-2^3 = -2 * -2 * -2$ .

$-2 * -2 * -2 = (-2 * -2) * -2 = (4) * -2 = -8$

Any negative base with an odd exponent will result in a negative answer, because, unlike even exponents and negative bases, the negatives will not cancel out.
