A negative or a posititve
two consecutive integers: x,x+1
x+(x+1) = 9(x) - 5(x+1)
2x+1 = 9x-5x-5
2x+1 = 4x-5
subtract 2x from each side
1 = 2x-5
add 5 to each side
6 = 2x
divide by 2
x=3
the integers are 3 and 4
Answer:
x=80
Step-by-step explanation:
Take the derivative of C(x) using the power rule
C'(x)=4x-320
Set this equal to 0 and solve for x
4x=320
x=80.
Sign analysis shows this to be a minimum because for values larger than 80 C'(x)>0 and for values less than 80 C'(x)<0
The correct answer is 0.312. Hope this helps!
