The original height of the plant is 20 inches, and each week for 4 weeks its height increases by 2h inches, so at the end of 4 weeks its height would be:
20 + 4(2h) = 20 + 8h
Now for the next two weeks the plant grows in height by h inches each week, so we need to add a further 2h inches to the equation. Thus the expression that shows the height of the plant after 6 weeks is:
20 + 8h + 2h = 20 + 10h, therefor A is the correct answer
hope this helps :)

To find the Y intercept, you need to change this equation into y=mx + b format. You can do this by subtracting 3x from both sides of the equation. This results in the equation of

If you are familiar with this format, it should be clear now that the Y intercept is - 2
5x + 9x + 26 = 180
14x = 180 - 26
14x = 154
x = 154 / 14
x = 11
answer
B. 11
This means that she has 4 hours of free time since 25% is 1/4 and it said that 25% was 1 hour so you mush multiply 1 to 4 since it has 4 parts and 1 hour is only the 1st part.
