In Mrs. Taylor's science class, the height of plants is recorded each week. The plants start at 10 cm tall and grow at a rate of 5 cm per week.

  1. Write the equation for the height hhh in centimeters as a function of the number of weeks www.
  2. What will the height be after 4 weeks?
  3. How many weeks will it take for the plants to reach 35 cm?

  • The equation is:

    h=5w+10


  • After 4 weeks:

    h=5(4)+10=30 cm


  • To find when the plants reach 35 cm:
    35=5w+10

  • w=5 weeks
