There must be a mistake in your question:
If 3 x ≤ 9, then : x ≤ 3 and :
x + 4 > 2
x > 2 - 4
x > - 2
Answer: D)
Solution set : - 2 < x ≤ 3
Answer:
<u>The four employees earned $ 452.80 in total</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Hour rate = $ 8.20
Overtime hour rate = $ 2.20 extra
Regular hours = 10
Overtime hours = 3
Number of employees = 4
2. How much money did they earn in total?
Let's find out the individual pay for an employee and then we'll calculate the pay for the 4 employees:
Individual pay = 10 * 8.20 + 3 * 10.40
Individual pay = $ 113.20
Total pay = Individual pay * 4
Total pay = 113.20 * 4
<u>Total pay = $ 452.80 </u>
Answer: A
Step-by-step explanation: If you subtract each price by the price lower then it. Ex: $19.95 - $15.96 = $3.99, $15.96 - $11.97 = $3.99 and so on. They all equal $3.99.
Simply you can substitute theta=45 degrees (or any angle,not zero) in left hand side and right hand side.
or
using a^2 - b^2 =(a+b)(a-b)
= sin(2x+x)sin(2x-x)
= sin 3x sin x
