Bruce should be glad he has parents to buy him stickers. Unless his last name is Wayne, then maybe Alfred is buying them for him... But what does stickers have to do with pencils? By the way, Alex has 45 pencils.
Answer:
(-2,3)
Step-by-step explanation:
Multiply -3x+4y=18 with 2:
-6x+8y=36
Add -6x+8x=36 and 6x+2y=-6
10y=30
y=3
So y=3 we can replace y with 3 on any of these two equations:
6x+6=-6
Move the 6 to the other side:
6x=-12
x=-2
So the solution is
(-2,3)
Hope this helps

The value of the second derivative for
is neither positive nor negative, so you can't tell whether this point is a minimum or a maximum. You need to check the values of the first derivative around the point.
But the value of
is always positive for
. That means at
there's neither minimum nor maximum.
The maximum must be then at either of the endpoints of the interval
![[-2,1]](https://tex.z-dn.net/?f=%5B-2%2C1%5D)
.
The function
is increasing in its entire domain, so the maximum value is at the right endpoint of the interval.
