Draw a sketch of a
graph that has one x-intercept.

Expresa commuter train leaves downtown sation and travels at a average speed of 55 miles per hour towards the north side sation, which is 50miles away. thirty minutes later, express commuter train #7 leaves north side and travels at a average speed of 35miles per hour towards downtown sation. at the moment the two trains pass each other, how far(in miles) is train #12 from the downtown sation and how long(in minutes) has the #12 train been traveling

Which number line represents the solution set for the inequality - x 24?

What happens to the area as the sliders are adjusted? what do you think the formula for the area of a triangle is divided by 2?
