Answer:
{x | x R, x > -5}
Step-by-step explanation:
Given:
![x-5>-10](https://tex.z-dn.net/?f=x-5%3E-10)
Add 5 both sides, we get
![x-5+5>-10+5\\x>-5](https://tex.z-dn.net/?f=x-5%2B5%3E-10%2B5%5C%5Cx%3E-5)
Therefore, the solution is
where, x is a real number.
So, {x | x R, x > -5} is the correct answer.
Answer: On the interval [25, 30] the function y = cos x is at it's minimum at x = 9pi or about 28.26.
The graph of y = cos x starts at 1 and moves in the shape of a wave from -1 to 1. It reaches it's first minimum value when x = pi. The period of the wave is 2 pi.
Therefore, it is at its lowest value at the following values, 1pi, 3pi, 5pi, 7pi, 9pi... The value in our given interval is 9pi.

whole numbers are 0,1,2,...
positive whole numbers 1,2,3...
a. ????=1
b.????=2
c. ????=4
d.(x-1)²(x+1)=0
(x²-1)(x-1)=0
x³-x²-x+1=0
x³-x²-x+2=1
