Students graphed the growth rate over several weeks of two plants in their classroom. The equations of both plants are given where x represents the time in weeks and y represents the heights of the plants in inches. Plant A: y = 1.8x + 3.1

Plant B: y = 2.3x + 1.9

Approximately how many weeks will it take for both plants to reach the same height? Round your answer to the nearest tenth.

1.9 weeks
2.4 weeks
3.1 weeks
7.4 weeks

What is the standard form of -5x^2+2x^4-11+x^3+3x

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
