@itsnotjesse the difference of c and 10 .... just the waqy you subtract \(2−3=-1\)
anonymous
  • anonymous
so it would be d right because you subtract @Koikkara
anonymous
  • anonymous
@Koikkara right?
anonymous

these are the four different weights: Weight 124.5 125.3 124.9 124.2 @itsnotjesse check which one is not \(below~.5\)
anonymous
  • anonymous
124.9 and 124.5 but i think its 124.9
Koikkara
  • Koikkara
Here, if the decimal value is \(= or < than~ 5, ~the ~decimal~value~changes~i.e,, \) 124.9=125. \(you~are~right~!!\) @itsnotjesse

next one, \(2x − 3y − z ,~x = −2, y = 3, ~z = −2\) substitute the values..
anonymous
  • anonymous
im sorry can you help me a bit more to jog my memory i dint remember how to do this
Koikkara
  • Koikkara
in place of x,y,z put the values, you are done
Koikkara
  • Koikkara
\(2x-3y-z=0\) \(2*(-2)-3*(3)-(-2)=0\)
anonymous
  • anonymous
so x,y,z i would replace them with -11 and see if it works and also with the others
Koikkara
  • Koikkara
\(-4-9+2\)= \(-11\) @itsnotjesse
anonymous
  • anonymous
so i was right the answer was -11
anonymous
  • anonymous
?
Koikkara
  • Koikkara
Yes
anonymous
  • anonymous
ok thank you can you help me with the last two?

@itsnotjesse next one... the point has the form of \((x,y)\) so there are 4 points given, can you tell me what is the maximum value of the y given ? ?
anonymous
  • anonymous
99.88
Koikkara
  • Koikkara
Correct, so we just need the y axis to be that long. so what interval of y you think we can take ?
anonymous
  • anonymous
25?
Koikkara
  • Koikkara
@itsnotjesse c'mon... you did everything by yourself yes..you are right
anonymous
  • anonymous
ok so it's B
Koikkara
  • Koikkara
Yes, and the last one, is here... http://openstudy.com/study#/updates/557f391ee4b07028ea60595b @itsnotjesse \(\color{blue}{\huge\tt{Nice~}}\) \(\huge\mathcal{to~meet~}\) \(\color{red}{\huge\tt{You~!}}\)
