Best ResponseYou've already chosen the best response.1#1, 2 are correct. #3 hint: x<4 is the same as x>4 (i.e. the direction of inequality is reversed when you negate an inequality) #4 "or" means either one works, so the two partanswers are additive #5 is correct #6 work out the two cases 2x+4>14 and 2x4>14 then take intersection of the two results, i.e. the part of the result that satisfies both cases. #7 draw on number line each option and figure out the right answer, which should be equivalent to 40<F<257 #8 is correct.

Best ResponseYou've already chosen the best response.1#3 3<x<6 is correct. Please state the values when checking the answer, instead of the letters. For #7, recognize that 5/9(F32) is the same temperature in Celsius. Also, all options have two separate inequalities, so you need the equivalent of 40<F, or 40<C, for the lower limit, and F<257 or C<125 for the upper limit. So check out each option to see which one has both conditions.

Best ResponseYou've already chosen the best response.1For #3, 3<x<6 would be correct. I will leave that to you to find the options! Remember that an empty dot refers to strict inequality, and a solid dot refers to >= or <=.

Best ResponseYou've already chosen the best response.140 F= 40 C furthermore: 125 °C= 257 °F I have used this formula: \[F = \frac{9}{5}C + 32\]

Best ResponseYou've already chosen the best response.1it is simple, you have to compute how many Fahrenheit degrees are these temperatures 40 C and 125 C

Best ResponseYou've already chosen the best response.040 C = 40 F 125 C = 257 F what would i do next ?

Best ResponseYou've already chosen the best response.1here we have to solve this inequality: \[  13 >  5x + 2 >  28\]

Best ResponseYou've already chosen the best response.1the first inequality is: \[  13 >  5x + 2\] whereas the second one is: \[  5x + 2 >  28\] please solve them

Best ResponseYou've already chosen the best response.1here, you have to solve these inequalities: \[\Large \begin{gathered} 4p + 1 >  7 \hfill \\ 6p + 3 < 33 \hfill \\ \end{gathered} \] what do you get?

Best ResponseYou've already chosen the best response.0can you teach me find the 2 inequalities so that i can solve 6 please? @Michele_Laino

Michele_Laino

Best ResponseYou've already chosen the best response.1the proposed inequlity is equivalent to these two systems of inequalities: \[\Large \left\{ \begin{gathered} 2x + 4 < 14 \hfill \\ 2x + 4 \geqslant 0 \hfill \\ \end{gathered} \right. \cup \left\{ {\begin{array}{*{20}{c}} {  2x  4 < 14} \\ {2x + 4 < 0} \end{array}} \right.\] please solve them

Best ResponseYou've already chosen the best response.0for both them is (2,5) (9,2) @Michele_Laino right?

Michele_Laino

Best ResponseYou've already chosen the best response.1the first inequality gives x>9 and the second one gives x<2, so the intersection is: (9,2)

Best ResponseYou've already chosen the best response.1the first solution is correct!
