Answer:
centre is 2,-3
radius is 2 units
Step-by-step explanation:
I dont know how to find the equation
above answers are also guesses.
hope u don't mind
Set up your equation:
1 = 7x - 3
Add 3 to both sides:
7x = 4
Divide both sides by 7:
x = 4/7
Hope this helps!
Well, the interseciton of 2 planes would be a line, so it would be like line AB when it goes through the 2 points A and B
Just simplify them to a decimal by dividing the numerator by the denominator.
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}
