Answer:
A) x ≠ 0
B) x ≠ 3
Step-by-step explanation:
The domain is all the possible values of x such that f(x) exists.
A) f(x) = (x + 5) / x
x can't be 0 (can't divide by 0), so the domain of x is all values other than 0.
You can write this in interval notation:
(-∞, 0)⋃(0, ∞)
Inequality notation:
x < 0 or x > 0
Or simply:
x ≠ 0
B) f(x) = 1 / (x - 3)
x can't be 3 (can't divide by 0), so the domain of x is all values other than 3.
(-∞, 3)⋃(3, ∞)
x < 3 or x > 3
x ≠ 3
Answer:
Step-by-step explanation:
Payment per hour is $8
commission is 15%
Total number of hours worked for 2 weeks is 73 hours
Total sales=$2095
commission earned for 2 weeks:
15/100×2095
=$314.25
Total amount earned in 73 hours:
73×8=$584
Total amount earned in commission and wages:
584+314.25
=$898.25
Answer: the options that apply are
1) w(2w + 4)
5) 2w² + 4w
Step-by-step explanation:
The formula for determining the area of a rectangular garden ins expressed as
Area = length × width
The length of a garden is four more than twice its width, w. The expression for the length would be
Length = 2w + 4
Therefore, the expression that represents the area of the garden would be
w(2w + 4)
Expanding the brackets, it becomes
2w² + 4w
Think it should just be A B D C not sure though, try it
