WebMar 8, 2024 · Educational Inequality is about the disparity of access to educational resources between different social groups. Some examples of these resources include … Webx < (log 128) / (log 2), or x < 7, as required. But when the numbers are less than 1, the inequality sign seems to flip: If 0.6 ^ x < 0.8, then x (log 0.6) < log 0.8, so x < (log 0.8) / (log 0.6), or x < ~0.436829 This is incorrect, as x must be greater than (log 0.8) / (log 0.6) to satisfy the inequality. Can anyone explain to me why?

WebSo the fact that when you multiply by a negative number, you invert the inequality relation, is the same as saying that multiplication by a negative number is a strictly decreasing … WebMultiplication by negative numbers flips inequalities. Multiplication by positive numbers respects inequalities. If a < b and c < 0, then a c > b c; if d > 0, then a d < b d. You can deduce the case of reciprocals (which is more complicated than what you wrote) from this.
WebOct 11, 2024 · Since f ( x) = log x is monotonically increasing ( x > 0) and log 1 = 0, when the base is less than 1, log b is negative and you will need to flip the sign. By the change of base formula, this is equivalent to: n log ( 1 2) ( 1 2) > log ( 1 2) ( 1 4) n > 2 as you have already said.

WebMar 31, 2024 · In your case, you are applying the function $f (x)=\frac {1} {x}$ to both sides which actually only switches the inequality some of the time: for example $2>-2$, but $\frac12>-\frac12$ (more on this later $*$). Explanation of answer: You can think of a strictly decreasing function $f$ as a function which is always going downwards. WebWe flip an inequality symbol when we multiply or divide by a negative or take the reciprocal on both sides of an inequality.
