Let us say, the number is "a"
one less than "a" is ... well a - 1
2/5 of that will be... well, 2/5 * ( a - 1)
one more than "a" is... well a + 1
3/5 of that is.. hmmm 3/5 * (a + 1)
now, we're told that, the first expression is "less than" the second one, thus
solve for "a", or make it "x" if you wish, same thing anyway
Answer:
Well, the answer to 17 divided by 2635 is 155, however, the number in the box must be 850, I believe.
935 subtracted by 850 equals 85 divided by 17 equals 0.
I hope this was helpful!
45/100 = 9/20
Work: divide by 5
Negative Slope<span>. </span>If<span> a line has a </span>positive slope<span> (i.e. m > 0 ), then y always increases when x increases and y always decreases when x decreases. Thus, the </span>graph<span> of the line starts at the bottom left and goes towards the top right. Thus, as x increases by 3 , y decreases by 4 , and as x decreases by 3 , y increases by 4 .

Answer:
(a) The critical points of f are x=0 and x=3.
(b)f is decreasing on 
and f is decreasing on 
.
(c) Therefore the local minimum of f is at x=3
Step-by-step explanation:
Given function is
(a)
To find the critical point set f'(x)=0
The critical points of f are 0,3.
(b)
The interval are and .
To find the increasing or decreasing, taking two points one point from the interval (0,3) and another point .
Assume 1 and 4.
Now 
and 
Since 1∈ , f'(x)<0 and 4∈ , f'(x)>0
∴f is decreasing on and f is decreasing on .
(c)
Differentiating with respect to x
Now
and
Since f''(x)>0 at x=3
Therefore the local minimum of f is at x=3
