Answer:
The answer is the second option
Step-by-step explanation:
Let u=x^2.





Set this equal to x^2


or



or

Step-by-step explanation:
f(x) = y= -x²-x+6
When y is max, f'(x) = 0
f'(x) = -2x-1
Equating to 0,
-2x-1= 0
x= -1/2
Put the value of x in f(x)
y = -(-1/2)² -(-1/2) +6
= -1/4+1/2+6
= 6+1/2
y= 13/2
Round. 80531 to nearest thousands
= 81,000
Answer:
9 over -15
Step-by-step explanation:
you subtract the coordinates from each oth
The coordinate is a solution for the first system (x-2y=4). But the coordinate is not a solution for the second system.
