Answer:
-4/7, -1/3, -0.1, 0, 0.1
Step-by-step explanation:
For your answer the will be shown below
Unit rate= 9
Answer: 14/3 miles
Step-by-step explanation: Miles divided by hours gives speed
1/3÷1/6 = 2 mph
Distance= speed × time
2 1/3 is 7/3 7/3×2 = 14/3
Answer: 82 sq. units .
Step-by-step explanation:
Let A (9, −1), B (−1, 7), C(−5, 2), D(5, −6) are the vertices of rectangle.
Then we plot them on graph ( as provided in attachment)
Length = AB
units [By distance formula :
]
units
Width = BC =
units

Area = length x width
= 
Hence, the area of the rectangle is 82 sq. units .
You could interpret them as system of equation and answer the question easily
from A
-4x + y + x + w =1
write in same form from A
as this system has five variables and four of them are unknowns it means the unique solution is not possible
So, det (A) = 0
