A diesel train traveled to New York and back. The trip there took 12 hours and the
trip back took nine hours. It averaged 10
km/h faster on the return trip than on the
outbound trip. Find the diesel train's
average speed on the outbound trip.

Which function is increasing? o a. f(x)=(1/15)* o b. f(x)= (0.5)* o c. f(x)=(1/5)* o d. f(x) = 5*

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =

Sum is 17 and their difference is 3
