The function modelled by the height (x) of the tree is as follows:
y - 180 = (368 - 180)/(7 - 3) (x - 3)
y - 180 = 47(x - 3) = 47x - 141
y = 47x - 141 + 180 = 47x + 39
Therefore, after 10 years, the tree will be 47(10) + 39 = 470 + 39 = 509 cm tall
A parallel line is where you slope is the same but a different y-intercept.
y = 2x + 4
Answer:
Step-by-step explanation:
We have the four thickest books from the line plot given by
Two books of 
inch thick and the two books of 
inch thickness.
So when the two inch thick book is being piled on the top of a inch thick books.
Therefore, the total thickness of the pile of books is given by :
Therefore, the thickness of the pile is .
Answer:
The third option, -1/2(30) = -15
Step-by-step explanation:
If it decreases by 1/2, we know it has to be -1/2, and the days we are given are 30. We need to multiply -1/2 by 30 in order to find the water level after 30 days, which would be -15 (inches?) I hope this helped.
