Which is the graph of the linear equation y= -1/4 x + 3?

Lesechka [4]

We know that -1/4x means we have a negative slope, which excludes the 1st graph from our answer choices.
Second, we know that the y-intercept has to be 3, excluding the second and third graph.
This leaves us with the 4th graph as our answer

Apply the properties of integer exponents to identify all of the expressions equivalent to 1/8.

Alborosie

Answer:

The answers are A , C , D

Step-by-step explanation:

Lets revise the rule of exponent

* $a^{n}*a^{m}=a^{m+n}$

* $\frac{a^{m}}{a^{n}}=a^{m-n}$

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

* $(\frac{a}{b})^{-m}=(\frac{b}{b})^{m}$

Now lets solve the problem

We need all the expressions equivalent to $\frac{1}{8}$

∵ $2^{-3}=\frac{1}{2^{3}}$

∵ 2³ = 8

∴ $2^{-3}=\frac{1}{8}$

Answer A is equivalent to $\frac{1}{8}$

∵ 2³ = 8

Answer B is not equivalent to $\frac{1}{8}$

∵ 2³ = 8

∴ $\frac{1}{2^{3}}=\frac{1}{8}$

Answer C is equivalent to $\frac{1}{8}$

∵ $2^{2}*2^{-5}=2^{2+-5}=2^{-3}$

∵ $2^{-3}=\frac{1}{2^{3}}=\frac{1}{8}$

Answer D is equivalent to $\frac{1}{8}$

∵ $2^{-2}*2^{5}=2^{-2+5}=2^{3}$

∵ 2³ = 8

Answer E is not equivalent to $\frac{1}{8}$

<em>The answers are A , C , D</em>
