7x+2≤2(2x-4)+3
? what you want to know???
Is the inequality always, sometimes, or never true
7x + 2 ≤ 4x - 8 + 3 7x + 2 ≤ 4x - 5 7x - 4x ≤ - 5 - 2 3x ≤ - 7 7 x ≤ (-)-- 3
x = anything less-than or equal-too negative seven over three.
@hal_stirrup , I'll return the favor.
only if you dived by negative number than you reverse the sign!! inequality rule.
@Compassionate , thanks. kind of you.
Only if the 'x' is negative. Example: -3x < -3 = x > 1 On the other hand: 3x < -3 = x < 1, And the other rule: -3x < 3 = x > -1
sure . thats clear.
:) Glad I could help.
guys I'm still confused... is the inequality always, sometimes, or never true?
well the statement is somewhat not clear so. but this inequality is true.
It's sometimes true. Depending on what X is.
ok
10 For example, if x = --- , the statement is not true. 1000
thanks.
whats so important to know if the inequality always, sometimes, or never true???
it's my math h.w lolol
