When the exponent blank is applied to a nonzero base, the result is always 1

boyakko [2]

Answer:

zero (0)

when the exponent 0 is applied to a nonzero base, the result is always 1

Step-by-step explanation:

Acoording to the zero power rule, a non zero number raised to the power 0 is always 1:

$a^{0} =1$ whit $a=0$

Let's check this property using an example:

We know that a quantity over itself is always 1: $\frac{2}{2} =1$

We also know that a base without exponent is always raised to the power 1: $2=2^{1}$

Now, according to the division power rule $\frac{a^{m} }{a^{n}} =a^{m-n}$ , so $\frac{2}{2} =\frac{2^{1} }{2^{1} } =2^{1-1} =2^{0} =1$

HELP!!! WILL AWARD BRAINLIEST!!!

First, solve 10x + y = -20 for y: y = -20 - 10x

Next, substitute -20 -10x for y in the second equation:

-20 - 10x = 2x^2 - 4x - 16.

Rearranging, 2x^2 + 6x + 4 = 0

Simplifying, x^2 + 3x + 2 = 0

The roots of this poly eqn are -1 and -2. Therefore, x = -1 and x = -2.

One by one, subst. these x-values into y = -20 - 10x to find the corresponding y-values.

Your answers should look like this: (-1, y) and (-2, y) (different values for y).
