2/3 = 4/6
1 = 6/6
6/6 - 4/6 = 2/6

Solving the system of equations, it is found that a viable time that the trains are side by side is given by:
B. 15 sec
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the equations are:


They will be side by side when:


It's solution is a quadratic function with coefficients a = 14, b = -130, c = -1200, hence:



Time is a non-negative measure, hence option B is correct.

Answer:heya
Step-by-step explanation:
it is in the form... a raise to the power n / a raise to the power m = a raise to the power n-m..........
so 9 raise to the power 2/9 raise to the power 7= 9 raise to the power(2-7)
=9 raise to the power -5
=1/9 raise to the power 5
hope it helps
