Answer:
y = 3.8 - 0.2x.
Step-by-step explanation:
y = k - 0.2x where k is the thickness of the ice before the melting starts and x = the number of weeks.
When x = 7, y = 2.4 therefore:
2.4 = k - 0.2*7
k = 2.4 + 1.4 = 3.8.
So our equation is y = 3.8 - 0.2x.

Answer:
D. (1,6)
Step-by-step explanation:
Vertical line segment:
A vertical line segment has fixed x coordinate.
In this question:
Vertical line segment that is 4 units long and is connected to (1,2).
The x-coordinate is x = 1.
The y-coordinate can be y = 2 - 4 = -2 or y = 2 + 4 = 6.
(1,6) is one of the options, so the correct answer is given by option D.
Use system of equations. We know l=w+90 and 2w+2l=700. Substitute w+90 in for l and solve.
l=220
w=130
Answer:
Rope 4
Step-by-step explanation:
A yard is 3 feet and a foot is 12 inches, which means a yard is 36 inches. 9 is 1/4 of 36, so Rope 4 is exactly 9 inches long.
