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: Malik's total profit is $213
Step-by-step explanation:
2 * 45 = 90
2 * 65 = 130
130 - 90 = 40
3 * 85 = 255
3 * 126 = 378
378 - 255 = 123
5 * 5 = 25
5 * 15 = 75
75 - 15 = 50
50 + 40 + 123 = 213

Answer:
1) 5/6 + 2/5 = 37/30 2) 1/6 - 1/10 = 1/15
Step-by-step explanation:
1) 5/6 + 2/5
25+12/30
= 37/30
2) 1/6 - 1/10
5-3/30
2/30
simplify the fraction
= 1/15
