First, you need to add 15x to both sides in order to get y by itself. Then, you need to divide all the numbers by 12. Your answer should be Y=1.25x+7. I hope this helps!
Answer: equation: y= 7/4x - 3
slope: 7/4
Step-by-step explanation:
Answer:
x^4 +2 +x^-4
Step-by-step explanation:
The square of a binomial is a form worthy of memorization.
(a +b)² = a² +2ab +b²
<h3>Application</h3>
Here, you have a binomial with a=x² and b=1/x². Using these values in the pattern, we have ...
![\left(x^2+\dfrac{1}{x^2}\right)^2=(x^2)^2+2(x^2)\dfrac{1}{x^2}+\left(\dfrac{1}{x^2}\right)^2\\\\=\boxed{x^4+2+\dfrac{1}{x^4}}](https://tex.z-dn.net/?f=%5Cleft%28x%5E2%2B%5Cdfrac%7B1%7D%7Bx%5E2%7D%5Cright%29%5E2%3D%28x%5E2%29%5E2%2B2%28x%5E2%29%5Cdfrac%7B1%7D%7Bx%5E2%7D%2B%5Cleft%28%5Cdfrac%7B1%7D%7Bx%5E2%7D%5Cright%29%5E2%5C%5C%5C%5C%3D%5Cboxed%7Bx%5E4%2B2%2B%5Cdfrac%7B1%7D%7Bx%5E4%7D%7D)
