Answer:
Its actually C
Step-by-step explanation:
Answer:
inequality form: w<-1
interval notation: (-1)
if this is not what your looking for then this might help
53w+13<55w+16
get w to one side
subtract 53w from both sides
13<3w+16
get 3w by itself
subtract 16 from both sides
-3<3w
divided both side by 3 to solve for w
-1<w
or w>-1
i hope this helped
and if it helped plzzzz mark as brainlest im trying to level up thanks
Answer:
Part A: C, Part B: A, E, i, K 160 cm, A: 21, Use PEMDAS and you get 13 5/7.
Step-by-step explanation:
1.6 x 100 meters = 160 centimeters
3 x 7/1 = 21/1 = 21
I think -8 -64 but srry if wrong
Answer:
(-5, 0) ∪ (5, ∞)
Step-by-step explanation:
I find a graph convenient for this purpose. (See below)

When you want to find where a function is increasing or decreasing, you want to look at the sign of the derivative. Here, the derivative is ...
f'(x) = 4x^3 -100x = 4x(x^2 -25) = 4x(x +5)(x -5)
This has zeros at x=-5, x=0, and x=5. The sign of the derivative will be positive when 0 or 2 factors have negative signs. The signs change at the zeros. So, the intervals of f' having a positive sign are (-5, 0) and (5, ∞).
