Answer:
Step-by-step explanation:
Rewrite:
![\dfrac{1}{\sqrt[3]{n^2}}=9\\\\9\sqrt[3]{n^2}=1](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B%5Csqrt%5B3%5D%7Bn%5E2%7D%7D%3D9%5C%5C%5C%5C9%5Csqrt%5B3%5D%7Bn%5E2%7D%3D1)
Cube both sides:
Divide both sides by 729:
Take the square root of both sides:
Hope this helps!
2) The slopes and y intercepts should be the same. In other words, the system of equations should overlap infinitely (meaning the lines overlap as “one line”).
3) y=3x+1 and y=3x-1 can be used for a system with no solutions. No value of x can make the equations equal.
Feel free to ask any follow-up questions!
That is 6x³+18x²-3x²=6x³+15x²
<span><span /><span>Being able to express numbers in its equivalent
forms allows you to give more accurate and correct answers. By using
equivalents forms you may find a simply and easier way to solve the given
equation.
For example, in fraction, by simply expressing equivalent fractions with common
denominator, you can easily subtract and add the given numbers in an easy way.
There are a lot of numbers that are equivalent, and there are a lot of way to
solve a single problem to get a correct answer.</span></span>
R = 3%/year
Equation:r = (1/t)(A/P - 1)
Calculation:Solving our equation:r = (1/7)((5445/4500) - 1) = 0.03r = 0.03
Converting r decimal to R a percentageR = 0.03 * 100 = 3%/year
The interest rate required to get a total amount, principal plus interest, of $5,445.00 from simple interest on a principal of $4,500.00 over 7 years is 3% per year.
