I'd start by calculating the determinant of the coefficient matrix. That's a cubic in k. Then find the values of k that make this determinant 0.
<span>When the determinant is not 0, the system has a unique solution. </span>
<span>When the determinant is 0, the system is linearly dependent and has infinite solutions, or is inconsistent and has no solutions. Which option depends on the constants on the right. </span>
<span>So take each value of k that makes the system 0, and see whether the equations are identical or inconsistent. </span>

I think it is B hope it is right
The answer is going to be exponents, I think. Not to sure though.
Hope this help! :)
Answer:The answer is 40 apples.
Step-by-step explanation:
