If n^-2 = 1/16, then n could be which of the following?

Zepler [3.9K]

Answer:

The correct choice is

$\boxed{n=4}$

Step-by-step explanation:

The given equation is

$n^{-2}=\frac{1}{16}$

We rewrite the left hand side of the equation as a power(a number to a given exponent.

$n^{-2}=\frac{1}{4^2}$

Recall that;

$\frac{1}{a^m}=a^{-m}$

We apply this property to obtain;

$n^{-2}=4^{-2}$

Since the exponents are the same, the bases are also the same.

Therefore $n=4$

5(x+6)-2x=3(x+10) solve for x

Drupady [299]

Answer:

x=all real numbers

Step-by-step explanation:

1. distribute: 5(x+6)-2x=3(x+10)

5x+30-2x=3x+30

2. combine like terms 3x+30=3x=30

3. these are equal therefore x=all real numbers

4. Two points on a line are (-10, 1) and (5, -5). If

Vsevolod [243]

Answer:

The x-coordinate of another point is zero

Step-by-step explanation:

step 1

Find the slope between the two given points

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

$(-10,1),(5,-5)$

substitute in the formula

$m=\frac{-5-1}{5+10}$

$m=\frac{-6}{15}$

Simplify

$m=-\frac{2}{5}$

step 2

Find the x-coordinate of another point

we have

(x,-3)

we know that

If the other point is on the line, then the slope between the other point and any of the other two points must be the same

so

Find the slope between the points

$(x,-3),(5,-5)$

Remember that

$m=-\frac{2}{5}$

substitute in the formula

$-\frac{2}{5}=\frac{-5+3}{5-x}$

$-\frac{2}{5}=-\frac{2}{5-x}$

the denominators must be the same

$5=5-x$

$x=0$

therefore

The x-coordinate of another point is zero
