A railroad crew can lay 6 miles of track each day. They need to lay 168 miles of track. The length, L (in miles), that is left to lay after d is given by the following function. L(d)=168-6d How many days will it take the crew to lay all the track? How many miles of track does the crew have left to lay after 17 days?

Consider the reaction 2x2y2+z2⇌2x2y2z which has a rate law of rate= k[x2y2][z2] select a possible mechanism for the reaction.

The table shows the balance of a money market account over time. write a function that represents the balance y (in dollars) after t years.

Consider this equation. |y + 6| = 2 what can be concluded of the equation? check all that apply. there will be one solution. there will be two solutions. the solution to –(y + 6) = 2 will be also be a solution to the given absolute value equation. the solution(s) will be the number(s) on the number line 2 units away from –6. the value of y must be positive since the variable is inside absolute value signs.
