(2y + x) + (2y + x) = (-2y + x) + (2x - 15)
2y + x + 2y + x = -2y + x + 2x - 15
4y + 2x = -2y + 3x - 15
+2y + 2y
6y + 2x = 3x - 15
-2x -2x
6y = x - 15
+15 +15
15 + 6y = x
Given:
buy a house in 9 years.
Estimated cost of the house = 175,800
down payment = 20%
closing cost = 7%
down payment:
175,800 x 20% = 35,160
closing cost:
175,800 x 7% = 12,306
Amount to save: 35,160 + 12,306 = 47,466
monthly savings:
9 years x 12 months = 108 months
47,466 / 108 = 439.50 savings per month.
Answer:
see below
Step-by-step explanation:
Part A
Since the lines goes through the point (0,0) the graph is proportional. We can find the rate of change by take the price of corn and dividing by the number of bushels
24/3 = 8 dollars/ bushel
Part B
Previous Year Number of Bushels Price of Corn (dollars)
3 21
6 42
9 63
12 84
We can find the rate of change for the previous year by using the slope formula
m = (y2-y1)/(x2-x1)
m = (84-63)/(12-9)
=21 / 3
= 7
The previous year was 7 dollars per bushel
The increase was 8-7 = 1 dollar per bushel
