Answer: Because 4 is the base of what is being exponentially multiplied, you can multiply 256 by 4 to get 4^5

Hi there! Hopefully this helps!

--------------------------------------------------------------------------------------------------------

<em>So, we know that 4 to the 4th power equals 256.</em>

<em />

<em>4 to the 4th power = 4 x 4 x 4 x 4.</em>

<em />

<em />

<em>So we can </em><u><em>add another 4 to the equation</em></u><em> to quickly get out answer for 4 to the 5th power.</em>

<em />

<em />

<em>4 to the 5th power = 4 x 4 x 4 x 4 x </em><u><em>4</em></u><em> = 1024.</em>

<em />

<em>~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~</em>

<em />

<em>Or you could break the equation into parts.</em>

<em />

<em>For example, there are </em><em>FOUR 4s</em><em> in the equation.</em>

<em />

<em>4 x 4 = 16.</em>

<em>4 x 4 = 16.</em>

<em />

<em>16 x 16 = 256.</em>

<em />

<em>Now since we've </em><em>added ANOTHER 4,</em><em> it should look like this:</em>

<em />

<em>16 x 16 = 256.</em>

<em />

<u><em>256 x </em></u><u><em>4 </em></u><em>= 1024.</em>

<em />

Solve this following system by graphing <br> X-y=4<br> X+y=2
OverLord2011 [107]

Answer:

The answer is x = 3 and y = -1

Step-by-step explanation:

If you were to graph the two lines, their equations would be y = x - 4 and y = -x + 2. The two lines intersect at the point (3, -1), so the solution to the system is x = 3 and y = -1.

Which statement about this system of equations is true? A. The system has no solution. B. The system has a unique solution at (0
SCORPION-xisa [38]

Answer:

A. The system has no solutions

Step-by-step explanation:

Step 1: Check to see if the 2 lines share 1 slope

slope of blue line = \frac{y2-y1}{x2-x1} =\frac{7-6}{3-0}=\frac{1}{3}

slope of red line = \frac{y2-y1}{x2-x1} =\frac{-3-(-4)}{3-0}=\frac{1}{3}

Step 2: Realize that lines with the same slope never touch

We know lines with the same slope are parallel to each other so they won't collide

Step 3: Know what the question is asking you

When they ask for solutions to the system of equations they are asking you to find out where they intersect

Step 4: Find answer

Because we know this is a parallel line they will never intersect causing this system to never have an answer or solution

Therefore the answer is A. The system has no solutions

Answer:

i think this is the answer aha

to get from 5 to 55 you times by 11

so i think to get from 11.8 to x you do the same thing and multiply by 11.

11.8×11=129.8

so x= 129.8

i think aha
