Answer:
"minimum value = 0; maximum value = 8"
Step-by-step explanation:
This is the absolute value function, which returns a positive value for any numbers (positive or negative).
For example,
| -9 | = 9
| 9 | = 9
| 0 | = 0
Now, the domain is from -8 to 7 and we want to find max and min value that we can get from this function.
If we look closely, putting 7 into x won't give us max value as putting -8 would do, because:
|7| = 7
|-8| = 8
So, putting -8 would give us max value of 8 for the function.
Now, we can't get any min values that are negative, because the function doesn't return any negative values. So the lowest value would definitely be 0!
|0| = 0
and
ex: |-2| = 2 (bigger), |-5| = 5 (even bigger).
So,
Min Value = 0
Max Value = 8
Answer:
285.12
Step-by-step explanation:
discount amount = 45/100 x 480= 45x48/10
=216.0
price after discount= 480-216=264
sales tax= 8/100 x 264=21.12
total money spent = 264+21.12=285.12
Answer: Manal = 27 messages
Elisa = 17 messages
Abdulrahman = 51 messages
Step-by-step explanation:
Let tye number of messages that Manal sent be x.
Since Eissa sent 10 fewer messages than Manal, this will be:
= x - 10
Abdulrahman sent 3 times as many messages as Eissa. This will be:
= 3(x - 10) = 3x - 30
We are also told that Manal, Abdulrahman, and Eissa sent a total of 95 text messages. This will be:
x + (x - 10) + (3x - 30) = 95
x + x - 10 + 3x - 30 = 95
x + x + 3x - 10 - 30 = 95
5x - 40 = 95
5x = 95 + 40
5x = 135
x = 135/5
x = 27
Manal = x = 27
Elisa = x - 10 = 27 - 10 = 17
Abdulrahman = 3x - 30 = 3×27 - 30 = 81 - 30 = 51
Manal = 27 messages
Elisa = 17 messages
Abdulrahman = 51 messages
