Answer:
B (300, 400)
Step-by-step explanation:
The profit maximization will be when the sum of the products will be greater. The maximum profit will be when x is 300 and y is 400. If we put in the equation :
P = 40x + 55 y
A - When x = 0 , y = 500
P = [40 * 0] + [55 * 500]
P = 27500
B -
When x = 300 , y = 400
P = [40 * 300] + [55 * 400]
P = 34000
C -
When x = 380 , y = 200
P = [40 * 380] + [55 * 200]
P = 26200
D -
When x = 400 , y = 0
P = [40 * 400] + [55 * 400]
P = 16000
Answer:
L = 3.9
Step-by-step explanation:

L = 3.9
substitute every x in the equation with (-2)
f(-2)=3*2*(-2) = -12
dunno if I get your equation correctly, pls check how you have written it
The line on the left with the arrow at the end.
One end is filled in meaning

and there is an arrow showing it goes on forever
The line is behind -2 and all numbers in it are
J-10=35
add 10 to both sides of the equal sign to isolate j
j=45
