Answer:
(4x-32),-2,1-13)6
Step-by-step explanation:
It all depends on the speeds of the cars. If they are going the same speed, the lines could never cross. Or they could could cross once, if one car passes the other.
However, if the speeds are changing, then there could be multiple solutions.
Answer:
Yes he did break the speed limit
Step-by-step explanation:
If he stuck to the speed limit it would have taken him 6 hours to go 540 kilometers
i can not give the answer unless you still cannot find it after these steps but I have steps that might help
1. Set the matrix (must be square).
2. Reduce this matrix to row echelon form using elementary row operations so that all the elements below diagonal are zero.
3. Multiply the main diagonal elements of the matrix - determinant is calculated.
