#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 part-answers are additive #5 is correct #6 work out the two cases 2x+4>14 and -2x-4>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

@mathmate for 3 it would be D right? and can you help me figure out 7 please?
anonymous

and let me rephrase that. for 3 it would be A right? @mathmate

-40 F= -40 C furthermore: 125 °C= 257 °F I have used this formula: \[F = \frac{9}{5}C + 32\]

@Michele_Laino can you help me figure the ones that are not correct out please?
Michele_Laino
  • Michele_Laino
it is simple, you have to compute how many Fahrenheit degrees are these temperatures -40 C and 125 C
anonymous
  • anonymous
-40 C = -40 F 125 C = 257 F what would i do next ?
anonymous
  • anonymous
@Michele_Laino i know its either A or B now
Michele_Laino
  • Michele_Laino
It is option B)

thankss!! can you help me out with #3?

  • Michele_Laino
here we have to solve this inequality: \[ - 13 > - 5x + 2 > - 28\]
Michele_Laino
  • Michele_Laino
actually, they are two inequalities
anonymous
  • anonymous
what would they be? @Michele_Laino
Michele_Laino
  • Michele_Laino
the first inequality is: \[ - 13 > - 5x + 2\] whereas the second one is: \[ - 5x + 2 > - 28\] please solve them

first: X>3 second: X<6 correct? @Michele_Laino

yes! correct!

THANK YOUUU! look. i know I'm really annoying and everything but can you please help me with 4? @Michele_Laino
Michele_Laino

here, you have to solve these inequalities: \[\Large \begin{gathered} 4p + 1 > - 7 \hfill \\ 6p + 3 < 33 \hfill \\ \end{gathered} \] what do you get?
anonymous
  • anonymous
P>-2 P<5 @Michele_laino
Michele_Laino
  • Michele_Laino
so, what is the right option?
anonymous
  • anonymous
@Michele_Laino i don't know. the person up there said it wasn't A so i don't know
Michele_Laino
  • Michele_Laino
I think it is A
anonymous
  • anonymous
can you teach me find the 2 inequalities so that i can solve 6 please? @Michele_Laino
Michele_Laino
  • Michele_Laino
the 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
anonymous
  • anonymous
for both them is (-2,5) (-9,2) @Michele_Laino right?
Michele_Laino
  • Michele_Laino
the first inequality gives x>-9 and the second one gives x<-2, so the intersection is: (-9,-2)
Michele_Laino
  • Michele_Laino
the first solution is correct!
Michele_Laino
  • Michele_Laino
more precisely the first solution, is: [-2,5)

quick question though. theres a point on a -5 on the number line and you got a -2.... is it supposed to be like that? @Michele_Laino
Michele_Laino
  • Michele_Laino
I don't understand, please specify more
