For which of the following inequalities is x => 4 a solution? x + 3 => 1 3x= > 1 x - 3= > 1
=> is the sign with A less than, bigger than, with the line under,
This ones' fun >.> \[x \ge 4\] This is similar to a one step equation What we have to do is SOLVE the inequality to see if it gives the final answer as x => 4 So \[x + 3 \ge 1\] We subtract 3 from both sides
Now we simplify (: \[x \ge -2\]
This inequality didn't give us the value of x => 4 So we can eliminate this answer choice
So far, do you get what Im saying?
We're doing Inverse operations to where we can get x by itself
Yeah sorry lol
\[3x \ge 1\] Inverse operations >.> 3x means multiplication meaning we divide 3 on both sides which gives you the inequality : \[x \ge \frac{ 1 }{ 3}\]
Which now leaves you with \[x - 3 \ge 1\] Keyword: INVERSE meaning OPPOSITE - 3 is a negative number you can also say it's subtraction, opposite of subtractuon is addition You add 3 on both sides 3 and 3 cancel out which leaves x by itself 3 + 1 = 4 Now we simplify \[x \ge 4\] The inequality: \[x - 3 \ge 1\] When we do inverse operations, the solution is \[x \ge 4\] Which is what the question is asking for
Your answer is The inequality \[x - 3 \ge 1\] give you the solution \[x \ge 4\]
Ohhhhhhhhhhhhhh ty
Do you understand tho? xD
Kindaaaaaaaa
And you're welcome
x≥4 this means? lol
Kinda- Lemme *simplify* it- math puns smh When having an inequality, you find the solution by using inverse operations For example the inequality x - 3 => 1 To get x by itself, we have to "remove" the number 3 We add 3 on both sides, we add because of inverse operations When we simplify we get x => 4 (:
Thats the equation...
if the sign faced towards the 4 It would mean the number that will be in place of the variable x is equal to or less than 4
OHHHHHHHhhh
YESS XD
When we remove the greater than sign we get x = 4 But in this problem, It's what we call an inequality, meaning we have a greater than or less than sign included
Does that make more sense?
Yes
Glad to help!
We can do the rest tomorrow xD
Ight xd
Thank you so much you don't know how much this means to me lol
You're welcome and anytime xd
