Answer:
x=7/5
Step-by-step explanation:
We can write it in exponential form
128= 2^2*2x * 2^x
2^4x+x=5x
2^5x=128
2^5x=2^7
5x=7
x=7/5
The value of x in the equation given is
[tex] \frac{7}{5} [/tex]
To solve :
[tex]128 = {4}^{2x} \times {2}^{x} [/tex]
Change all values to have the same root :
[tex] {2}^{7} = {2}^{2(2x)} \times {2}^{x} [/tex]
[tex] {2}^{7} = {2}^{4x} \times {2}^{x} [/tex]
[tex] {2}^{7} = {2}^{(4x + x)} [/tex]
[tex] {2}^{7} = {2}^{5x} [/tex]
The roots cancel out
[tex] 7 = 5x[/tex]
Divide both sides by 5
[tex]x = \frac{7}{5} [/tex]
Therefore, the value of
[tex]x = \frac{7}{5} [/tex]

factor the
Answer:
The answer is 3(3m-2)^2
Step-by-step explanation:
We have the following expression:
[tex] {27m}^{2} - 36m + 12[/tex]
We can take common factor 3 and we got.
[tex]3( {9m}^{2} - 12m + 4)[/tex]
We can factorize and we got:
[tex]3(3m - 2)(3m - 2)[/tex]
Then the final answer is:

You found Genie hidden in a dungeon. Genie is offering two different options for you as a reward for finding him. There are two options shown for you to choose.
Which option would you choose? Explain your reasoning using the key features of exponential functions.
Answer:
The first option is
A(x) = 10000(1.05)ˣThe second option is:
B(0) = 1000B(1) = 1100The ratio is 1.1 and the zero term is 1000The equation for this option is:
B(x) = 1000(1.1)ˣNow, which option is better?
It depends on the number of x. It is assumed the genie is offering money or similar reward.
For the values of x below 50 option A is better and option B is much better for x > 50.
See the graph in the attachment, where green line represents the option A and red line is option B.

Write in equation in slope form of the line shown
Answer:
y=2x-5
Step-by-step explanation:
Slope intercept form is y=mx+b, with m being the slope and b being the y-intercept.
Slope is found through (y2-y1)/(x2-x1) and when the values are plugged in you get (-3-1)/(1-3) which equals -4/-2 or 2.
y=2x+b
Since b is the y-intercept, you plug in the value of the point where the line crosses over the y axis. In this case, that value is -5, so you get y=2x-5.
