The daily low temperatures in a city have been below 0° Fahrenheit (F) for the past two days. On Monday, the daily low temperature was −2℉ and on Tuesday, the daily low temperature was −7℉. What is the absolute value of the change in daily low temperatures between these two days, in degrees Fahrenheit?
(This is math class btw)
Answer:
5ºF is the absolute value of the change.
Step-by-step explanation:
Since absolute value is alwasy positive you will not need the negative sign. The difference between 7 and 2 is 5, so the answer is 5.

2 horses ran from the same place from the at same time one horse ran at 2 miles per second and the other ran at a speed for 18 miles per second. how far apart were they in 1 minute? in 5 minutes? in 8 minutes?
- PLS HELP ASAP!!!!!
Answer:
1 minute = 1080 - 960 = 120 m
5 minutes = 5400 - 4800 = 600 m
8 minutes = 8640 - 7680 = 960 m
Step-by-step explanation:
I think the easiest way is to just see how far they get at each time. So I'm going to go one horse at a time.
16 m/s
1 minute = 60 seconds, every second is 16 meters so 16 m/s * 60 s = 960 m
5 minutes = 300 seconds so 16 m/s * 300 s = 4800 m
8 minutes = 480 seconds, 16 m/s * 480 s = 7680 m
I also want to point out that unites cancel out. m/s * s is kinda like variables so the seconds being multiplied by m/s cancels witht eh seconds in the denominator.
Now the next horse
18 m/s
1 minute totals to 1080 m
5 minutes = 5400 m
8 minutes = 8640 m
Now we take the differences of each time
1 minute = 1080 - 960 = 120 m
5 minutes = 5400 - 4800 = 600 m
8 minutes = 8640 - 7680 = 960 m
Another way to do this is to take the difference of speed and then multiply that by the time. so 18-16 = 2, then multiply each time by 2. For me it just makes more intuitive sense the way I showed.

Point A is located at (-3, -6) and is reflected in the y-axis. What is the location of Point A'?
O(-3,6)
O(3,6)
O (3-6)
O(-6, -3)
Answer:
O(3,6)
Step-by-step explanation:
If the points are (-3,-6), this means -3 on the x axis and -6 on the y axis. if it is reflected in the y axis, the coordinates Change from either positive to negative or negative to positive. This means -3 is now 3 and -6 is now 6 hence the coordinates of (3,6)

Step-by-Step Equation:
Answer:
8b^2 + 9b + 3y +5
Step-by-step explanation:
7b + 8b^2 + 3 + y + 2b + 2y + 2
8b^2 + 9b + 3 + y + 2y + 2
8b^2 + 9b + 3y + 3 + 2
= 8b^2 + 9b + 3y +5
NOTE:
the symbol '^' represents 'to the power of', so 8b^2 would be 8b to the power of 2.
