Option B is the correct answer since the rule of the inequality states that "if divided or multiplied by a negative, switch into the opposite of the inequality".

@@lyingcat9022hey fella! So the issue that occurs when we multiply or divide a negative number in inequalities is that negative numbers work opposite in comparison to positive ones, For ex: +3 is greater than +2 But -3 is smaller than -2 This causes an error in the inequality which is hence corrected by flipping the inequality. lets Take an example, 2x

Do we switch the inequality when we plus or minus or only when we divide or multiply
@carultch
5 ай бұрын
You only switch the inequalities when you do an operation that switches directions. You can subtract 8 from both sides without changing the inequality. Then when you divide by -5, you switch the inequality direction. If you had to flip both sides, like if you had the following, then you'd also reverse the inequality sign. 8 - 5/x >= -7 Subtract 8 from both sides, leave the inequality sign alone: -5/x >= -15 Divide both sides by -5, and flip the sign: 1/x = 1/3
@carultch
5 ай бұрын
The telltale sign of when you need to flip the inequality sign, is when the operation you do to both sides, has a negative derivative (or slope). Some examples: For adding or subtracting a constant, leave the inequality alone. This is because both of the following equations have a positive slope, regardless of whether c is positive or negative. y = x + c y = x - c For multiplying or dividing by a positive number, you leave the inequality alone. This is because: y = k*x, and y = 1/k * x, both have a positive derivative, where k is a positive constant >= 1. Whereas: y=-k*x, and y = -1/k * x, both have negative slopes, so you flip the sign if you multiply or divide by a negative. For reciprocaling both sides, since y=1/x has a negative derivative of dy/dx = -1/x^2, in this operation, you need to flip the sign. For squaring both sides, or square rooting both sides, where both sides start as positive numbers for the whole domain of interest, you leave the inequality sign alone. Since y=x^2 and y=sqrt(x) both have positive slopes. Squaring both sides is risky, because it removes the information that one of the sides might've been negative.

doesn’t the inequality sign act as a equal sing giving it the same properties of an equal ding making the switch from a -5 to a positive when dividing both sides?
@polygontower
Ай бұрын
Dividing or multiplying by a negative number flips the sign. For example, -2x < -10. Say that -2x in this case is -20, which is less than -10. Let's solve for x by dividing by -2 on both sides. x

Hii, your method is WRONG In the rules of inequalities we are not allowed to do this. I suggest anyone who doesn't want to loose marks should not do this. This is the correct method (for a similar question) 8-5x>-7 8>-7+5x 8+7>5x 15>5x 3>x (Both answer are the same where x is small however in inequalities we are not allowed to use this method and can loose marks)

Such weird way how americans solve equations , very very time consuming , just swing the 8 to the right and you gell -5x>_ -7 -8 Abd the swing to 5 to the denominator, youll get x >_ -15/-5 So instead of subtracting adding divinding each side just swing the no. Left and right , less time consuming and that way youll be able to solve quickly in your head

@@misskitty_0 You don't have to do it this way once you get more advanced. You might be able to do this particular simple example in your head, but to prepare you for the much more complicated examples, you want to learn to understand how to show the steps. This is more to show students who are first learning algebra, to understand what they are doing. If your target audience has been familiar with algebra for years, you don't need to specifically say "subtract 8 from both sides, divide both sides by -5". You can simply say "make x the subject", or "isolate x", and everyone will know what you mean.
