In this case,
A square on a coordinate plane moves down by 
units and to the right by 
unit.
This implies that
the translation rule is
thus,
the right option is A
T1, –9(x, y)
For the given data set reflecting the number of rings each individual is wearing: 0,2,4,0,2,3,2,8,6, the interquartile range is determined to be 2. Here, Q1 equals 4, the median or Q2 is 3, and Q3 is 6. The method for calculating the interquartile range is IQR = Q1 - Q2.
Answer: The hourly charge for the rototiller is $3.
Step-by-step explanation:
Let h denote the hourly rate for the rototiller rental.
The rental provider imposed a base fee of $43 in addition to a charge per hour. Assuming the rototiller was rented for x hours, the cost incurred would total
43 + hx.
If they paid $64 for 7 hours of rental, the equation representing this situation would be
43 + 7h = 64.
Resolving gives us 7h = 64 - 43 = 21.
Therefore, h = 21/7 = $3.
