You would basically go back and trace all your steps, that's what I do. And if your answer seems reasonable then you have the right answer but if your work doesn't match the answer than you've messed up.
I hope I helped if I did like my answer and comment down below thx
Slope intercept form
y = mx+b
y = -7x + 9
m = -7
Answer: k=54/79
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
Step 2: Subtract 16/3k from both sides.
Step 3: Subtract 5/2 from both sides.
Step 4: Multiply both sides by 12/(-79).

Answer:

Step-by-step explanation:
Given expression is ,
This would be simplified using the law of exponents , some of which I will use here are ,
Using the above laws ,
Using the second law mentioned above , we have,
![\sf \longrightarrow \bigg[ \dfrac{1}{4}(x^{3+2})(y^{-5-6})(z^{8-3})\bigg]^{-2}](https://tex.z-dn.net/?f=%5Csf%20%5Clongrightarrow%20%5Cbigg%5B%20%5Cdfrac%7B1%7D%7B4%7D%28x%5E%7B3%2B2%7D%29%28y%5E%7B-5-6%7D%29%28z%5E%7B8-3%7D%29%5Cbigg%5D%5E%7B-2%7D%20)
Simplify ,
![\sf \longrightarrow \bigg[\dfrac{1}{4} x^5y^{-11}z^5\bigg]^{-2}](https://tex.z-dn.net/?f=%5Csf%20%5Clongrightarrow%20%5Cbigg%5B%5Cdfrac%7B1%7D%7B4%7D%20x%5E5y%5E%7B-11%7Dz%5E5%5Cbigg%5D%5E%7B-2%7D%20)
Using the first law mentioned above , we have,
![\sf \longrightarrow \bigg[ \dfrac{1}{4^{-2}} x^{5(-2)} y^{-11(-2)} z^{5(-2)}\bigg]](https://tex.z-dn.net/?f=%5Csf%20%5Clongrightarrow%20%5Cbigg%5B%20%5Cdfrac%7B1%7D%7B4%5E%7B-2%7D%7D%20x%5E%7B5%28-2%29%7D%20y%5E%7B-11%28-2%29%7D%20z%5E%7B5%28-2%29%7D%5Cbigg%5D%20)
Simplify,

Finally using the fourth law mentioned above , we have ,
