Ms.Koehler is planting A treat to help save the environment. She decided to keep track of the height of the tree over the years. After the first year Ms. Koehler measured the tree to be 8 feet tall. She took note that this was an increase of 3 feet from the previous year. Assuming the tree will continue to grow at this rate I answer the following questions.


Write an equation representing the height of Ms. Koehler’s three overtime, where y represents the height of the tree and x is the number of years since being planted

Answers

9514 1404 393

Answer:

  y = 3x +5

Step-by-step explanation:

We are told the height increase is 3 ft in 1 year. That is the slope of the linear function representing height.

We are told that in year 1 the height was 8 ft, and that it was 3 ft less in the previous year. That is, it was 5 ft high in year 0. So, the y-intercept of the function is 5.

The slope-intercept equation is ...

  y = mx + b . . . . for slope m and y-intercept b

  y = 3x + 5

Katrina bought a new sofa. She was able to pay $100 at the
time she received the sofa. She will pay $22 each month on
the balance. The original cost of the sofa was $298. The
equation 100 + 22 = 298 represents this situation.
Use the equation to determine how many months will it take
Katrina to pay off the sofa.

Answers

Answer:  9 months

================================================

Work Shown:

100 + 22x = 298

22x = 298-100  ........ subtracting 100 from both sides

22x = 198

x = 198/22 .............. dividing both sides by 22

x = 9

It will take 9 months for her to pay off the sofa.

She pays the original $100, and then on top of that, she pays an extra 22*x = 22*9 = 198 dollars since she paid $22 per month for 9 months. So this leads to 100+198 = 298 dollars total to help confirm our answer.
