Answer:
See below.
Step-by-step explanation:
This is conveniently done using a 24-hour representation of the given time:
... 2:30 pm = 14:30
Honolulu = 14:30 -10 = 4:30 . . . . 4:30 am
London = 14:30 - 0 = 14:30 . . . . 2:30 pm
Los Angeles = 14:30 -8 = 6:30 . . . . 6:30 am
Paris = 14:30 +1 = 15:30 . . . . 3:30 pm
Tokyo = 14:30 +9 = 23:30 . . . . 11:30 pm
Washington = 14:30 -5 = 9:30 . . . . 9:30 am
Answer:
Step-by-step explanation:
7x - 4 = 5x - 10
2x - 4 = -10
2x = -6
x = -3
Answer: The temperature will be 36.4 degrees.
Step-by-step explanation:
Hi, to answer this question we have to subtract the product of the temperature decrease per week (-1.3) and the number of weeks (12) to the actual temperature (52).
Mathematically speaking:
52 - (1.3 x 12)
Solving:
52-15.6
36.4 degrees
The temperature will be 36.4 degrees.

Need a little more info for the fist part but 34-17 is 17
Answer:
Given:
A set of functions,
A. y = -(x-4)^2
B. y=3(x- 4)^2
C. y = [x] + 4
D. y = -5x + 4.
To Find:
The function whose range is (-infinity, 4].
Solution:
1. The function y = -(x-4)^2 has a minimum value of 0 and it is an increasing function. Hence the maximum value tends towards infinite. Hence the range is [0, infinite).
2. The function y = 3(x-4)^2 has a minimum value of 0 and it is an increasing function. Hence the maximum value tends towards infinite. Hence the range is [0, infinite).
3. y = [x] + 4 (where [x] = greatest integer function). This function is an increasing function with a minimum value towards negative infinity and the maximum value tends towards the positive side of infinity.
=> Range of y = [x] + 4 is (-infinite, infinite).
4. y = -5x+4 is a continuous increasing function without any exceptions.
=> Range of y = -5x+4 is (-infinite,infinite)
Therefore, none of the functions has their range from (-infinity,4].
