I believe Groceries is since groceries can be changed and prices can be altered more easily than the other three options. Can't explain that well, hope I helped!
Answer:
1
Step-by-step explanation:
Part d
∫f′(t)dt as long as the function is continuous
Let u = 6-2x
du = -2dx so -1/2 du = dx
upper limit = 6- 2(4) = 6-8 = -2
lower limit = 6 - 2(2) = 6 - 4 = 2
∫f′(u)(-1/2)du limits -2 to 2 =-1/2( f(-2) - f(2))
f(-2) is 1
f(2) is 3
-1/2(f(-2) - f(2)) = -1/2( 1-3) = -1/2(-2) = 1
Answer:
The factors of 
are ![[(x-y)(x^{2}+xy+y^{2})]](https://tex.z-dn.net/?f=%5B%28x-y%29%28x%5E%7B2%7D%2Bxy%2By%5E%7B2%7D%29%5D)
.
Step-by-step explanation:
We know that:
Compute the factors of as follows:
Thus, the factors of are .
Answer:
x=7, y= 8
Step-by-step explanation:
x+y=15
x+2y=23
Subtract the first equation from the second equation to eliminate x
x+2y=23
-x-y=-15
--------------------
y = 8
Now we can find x
x+y = 15
x+8 = 15
Subtract 8 from each side
x+8-8=15-8
x = 7
