Its 2.8, just multiply?<span />
Part A
5x - 5 >= 10 or-3x + 1 > 13
1) This is a disjunction (OR)
5x - 5 >= 10
5x >= 15
x >= 3
or
-3x + 1 > 13
-3x > 12
x < -4
Answer
x <- 4 or x >= 3
Part C:
1) This is a conjunction (And)
5x+ 3 <= 18 and 4 - x < 6
5x <= 15 and - x < 2
x <= 3 and x > -2
Answer
-2 < x <= 3
Here, Rational numbers are: = 2/9 and √225
& other two are irrational
Hope this helps!
9^7=4782969 and 3^12=531441 and when you add 4782969 and 531441 together you get 5314410. Then divide that number by 90 and get 59049
