Answer:
-4,0 -4,0
Step-by-step explanation:
-4,0 -4,0
From 8.30 pm to 12 : 00
Difference = 12 : 00 - 08:30 = 3 : 30
3 hours 30 minutes = 3.5 hours.
Total for those hours = 3.5 * 1000 = $3500
From 12:00 to 1:00 am = 1 hour.
50% increase = 50% of 1000 = .50 * 1000 = 500
So it will increase to 1000 + 500 = $1500 per hour.
For the 1 hour extra, 1 * 1500 = $1500
Total = $3500 + $1500 = $5000
She will be paid $5000
4a^4 -2b^2 +40
a=2
b=7
4(2)^4 -2(7)^2 +40
PEMDAS is what your gonna use to solve this you go from right to left
First is P which is parentheses which is none
second is E which stands for exponents
4(32)-2(49)+40
now MD multiply or divide
128-98+40
now add or subtract
30+40
last one
70 this is your answer i hope
Answer:
![x > -1](https://tex.z-dn.net/?f=x%20%20%3E%20-1)
Step-by-step explanation:
Given
![-2(3x - 1) < 8](https://tex.z-dn.net/?f=-2%283x%20-%201%29%20%3C%208)
Required
Show on a number line
![-2(3x - 1) < 8](https://tex.z-dn.net/?f=-2%283x%20-%201%29%20%3C%208)
Divide through by -2
![\frac{-2(3x - 1)}{-2} < \frac{8}{-2}](https://tex.z-dn.net/?f=%5Cfrac%7B-2%283x%20-%201%29%7D%7B-2%7D%20%3C%20%5Cfrac%7B8%7D%7B-2%7D)
![3x - 1 > -4](https://tex.z-dn.net/?f=3x%20-%201%20%3E%20-4)
Add 1 to both sides
![3x -1 + 1 > -4 + 1](https://tex.z-dn.net/?f=3x%20-1%20%2B%201%20%3E%20-4%20%2B%201)
![3x > -3](https://tex.z-dn.net/?f=3x%20%3E%20-3)
Divide through by 3
![x > -1](https://tex.z-dn.net/?f=x%20%20%3E%20-1)
