960 feet per minute. 30 is half of one minute, so multiply 480 by two
Answer:
x is positive, and y is negative
Step-by-step explanation:
-60° is a fourth-quadrant angle, where x is positive and y is negative.
Answer:y=a+b times x
Step-by-step explanation:
what ever the x value represents you are going to multiply it by a
The number of seats sold cannot be negative, so you have
... x ≥ 0, y ≥ 0
The limits on numbers of seats must be observed, so you have
... y ≤ 2000
... x + y ≤ 3000
And the revenue constraint must be met:
... 35x + 50y ≥ 90,000
Together, these inequalties are ...
{x ≥ 0, y ≥ 0, y ≤ 2000, x + y ≤ 3000, 35x + 50y ≥ 90,000}
