Answer:
1) x= -36.
2) x = 0.
Step-by-step explanation:
1) Taking the 3rd power to both sides and using the following exponent law:

we get:

So this tells us that x = -36.
2) We can distribute the power inside every term. So the left side becomes:

Now, the trick here is to remember that
, so replacing 1 with
, which then gives us:
, telling us that 3x = 0 and thus, x = 0.

Hello!</h2>
The answer is:
The equation of the line in slope-intercept form:

<h2>
Why?</h2>
To find the equation in slope-intercept form, we need to follow the next steps:
Find the slope of the line:
Using the slope formula, we have:

We are given the points:

So, substituting we have:



Find the "b" value:
Now that we know the value of the slope, we can write the equation of the line:

In order to find "b" we need to substituite any of the given points, we know that line is thru both of the given points, so, substituting (2,4) we have:

Now that we know the slope and "b", we can write the equation of the line in slope-intercept form:

Have a nice day!

Answer:
9 years
Step-by-step explanation:
The simple interest formula is ...
I = Prt
where I is the interest earned on principal P invested at annual rate r for t years. Solving for t, we have ...
t = I/(Pr) = 1125/(2500×.05) = 1125/125
t = 9 . . . . years
It will take 9 years for Anna to earn 1125 in interest.
