Solve the inequality. 8x-5> _27. a. x> _4. b. x> _11/4. c. x< _4. d. x< _11/4
Answer from: esheagustafson
8x - 5 ≥ 27
8x ≥ 32 <-- Add 5 to both sides
x ≥ 4 <-- Divide both sides by 8
So, to be in solution set, x has to be greater or equal to 4.
In interval notation: [4, ∞)
In a set builder notation: {x | x ∈ R, x ≥ 4}
8x ≥ 32 <-- Add 5 to both sides
x ≥ 4 <-- Divide both sides by 8
So, to be in solution set, x has to be greater or equal to 4.

a 4/6 = 9/12 not proportional
step-by-step explanation:
to find which are not proportional, we can use cross products
if it is true, they are proportional. if it is not true, they are not proportional.
a 4/6 = 9/12
4* 12 = 6*9
48 = 54
not this is not proportional
b 2/3 = 12/18
2* 18 = 3 * 12
36 = 36
this is proportional
c 5/4 = 10/8
5*8 = 4*10
40 = 40
this is proportional
d 7/5 = 35/25
7*25 = 5 * 35
175 = 175
is proportional
