F(3) = (1/6)3 = 1/2
The answer is 1/2 or 0.5
X + 4y = 3 x = -4y + 3
2x - 3y = 17
2(-4y + 3) - 3y = 17
-8y + 6 - 3y = 17
-11y + 6 = 17
-11y = 11
y = -1
x = -4(-1) + 3
x = 4 + 3
x = 7
(7, -1) is your answer
Answer:
- domain: (-∞, ∞) \ (kπ+π/2 for integers k)
- range: (-∞, ∞)
Step-by-step explanation:
The tangent function is undefined at odd multiples of π/2. It can take on any value.
The domain is all real numbers except odd multiples of π/2.
The range is all real numbers.
Answer:
Step-by-step explanation:
If she sells 8 dozen, she will get exactly 120 dollars. But that is not what the question says.
Sales = 8 * 15 = 120
The question says that she wants to make more than 120 dollars. Therefore the circle must be an open one. B is the proper answer. A is close but A means that she is willing to stop her sales when they reach 120 dollars. Not so.
A is not the answer.
