Let's find out!
-5 + x * x + 4.
-5 + x^2 + 4.
-5 + 4 + x^2.
-1 + x^2.
5 + x * x - 4.
5 + x^2 - 4.
5 - 4 + x^2.
1 + x^2
So, they are NOT the same, because one of the "1"'s are negative, and the other is positive.
Answer:
(x, y) =(2,-3)
Step-by-step explanation:
4x+3y=-1
3x-9y=33 /:3
4x+3y=-1.....(1)
x-3y=11... (2)
(1)+(2): 5x=10
x-3y=11
x=10/5
x-3y=11
x=2
2-3y=11
x=2
-3y=11-2
x=2
-3y=9
x=2
y=9/(-3)
x=2
y=-3
(x,y)=(2,-3)
Answer:
The profit decreases by $ 375 for every $ 1 increase in the selling price.
Step-by-step explanation:
From the definition of the secant line we get that the average rate of change of , where is the selling price of the product, measured in dollars per unit, is:
(1)
Now we evaluate the function at each bound:
x = 50
x = 55
Then, the average rate of change is:
Hence, the profit decreases by $ 375 for every $ 1 increase in the selling price.
1/2 is the greater fraction
