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
The answer is the first one.

Answer:
30 inches
Step-by-step explanation:
using a^2+b^2=c^2
72^2=5184
30^2=900
5184+900=6084
√6084=78
Answer: Choice B) The probability of buying a taco OR a drink is 45%
The uppercase P means "probability". Using parenthesis with the P tells us "probability of whatever event happens"
P(A) means Probability of event A happening
P(B) means probability of event B happening
P(A or B) means Probability of event A or event B (or both) happening
You then replace A with "customer buys taco" and B with "customer buys drink" to get the answer mentioned above.
