What makes this statement true? 7^-2

MaRussiya [10]

For this case we have:

By definition, one of the properties of the power, known as negative integer power, states that:

$a ^{-b}$ can be written as $\frac{1}{a ^ b}$

Thus, $7 ^{-2}$ can be written as $\frac{1}{7 ^ 2}$ . So:

$\frac{1}{7 ^ 2}= \frac{1}{(7 * 7)}=\frac{1}{49}$

Answer:

Power of negative integer exponent:

$7^{-2} =\frac{1}{7 ^ 2}= \frac{1}{(7 * 7)}=\frac{1}{49}$

The equation 2(4x + 1) = 4(2x + 5) has no solutions. Which of the following best explains why?

Vladimir79 [104]

Answer:

See below

Step-by-step explanation:

$2(4x + 1) = 4(2x + 5)$

$8x + 2 =8x + 20$

$\nexists x \in \mathbb{R} \text{ That makes the equality true}$

The equation has no solution because no matter what the value we plug for $x$ in the equation, it will not be true and will lead to a contradiction. This is the meaning of not having a solution.

How does this work out?

Alona [7]

Slope= (y2-y1)/(x2-X1)

1=(9-3)/(3-x)
1=6/(3-x)
3-x=6
X=9
