3)Evaluate the following expression using the values given: Find 2x − 3y − z if x = −2, y = 3, and z = −2 −11 11 −15 15 4)Martin wants to plot a graph to show the prices of different numbers of helmets. He has to plot the following points: (1, 24.97), (2, 49.94), (3, 74.91), (4, 99.88) Which of the following best describes how the y-axis should be labeled? From 0 to 300 at intervals of 50 From 0 to 100 at intervals of 25 From 0 to 500 at intervals of 100 From 0 to 80 at intervals of 10 5)It took Everly 55 minutes to run a 10-kilometer race last weekend.

@Study_man can you help me

4. Koikkara

@itsnotjesse the difference of c and 10 .... just the waqy you subtract $$2−3=-1$$

5. anonymous

so it would be d right because you subtract @Koikkara

6. anonymous

@Koikkara right?

7. anonymous

@Koikkara ?

8. anonymous

@Study_man can you help me plz

9. Koikkara

@itsnotjesse yes $$c-10$$

10. anonymous

@Koikkara ok thank you and can you help me with any more ?

11. Koikkara

these are the four different weights: Weight 124.5 125.3 124.9 124.2 @itsnotjesse check which one is not $$below~.5$$

12. anonymous

124.9 and 124.5 but i think its 124.9

13. Koikkara

Here, if the decimal value is $$= or < than~ 5, ~the ~decimal~value~changes~i.e,,$$ 124.9=125. $$you~are~right~!!$$ @itsnotjesse

14. anonymous

@Koikkara ok thank you is that all or can you help with more

15. Koikkara

next one, $$2x − 3y − z ,~x = −2, y = 3, ~z = −2$$ substitute the values..

16. anonymous

im sorry can you help me a bit more to jog my memory i dint remember how to do this

17. Koikkara

in place of x,y,z put the values, you are done

18. Koikkara

$$2x-3y-z=0$$ $$2*(-2)-3*(3)-(-2)=0$$

19. anonymous

so x,y,z i would replace them with -11 and see if it works and also with the others

20. Koikkara

$$-4-9+2$$= $$-11$$ @itsnotjesse

21. anonymous

so i was right the answer was -11

22. anonymous

?

23. Koikkara

Yes

24. anonymous

ok thank you can you help me with the last two?

25. Koikkara

@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 ? ?

26. anonymous

99.88

27. Koikkara

Correct, so we just need the y axis to be that long. so what interval of y you think we can take ?

28. anonymous

25?

29. Koikkara

@itsnotjesse c'mon... you did everything by yourself yes..you are right

30. anonymous

ok so it's B

31. Koikkara

Yes, and the last one, is here... http://openstudy.com/study#/updates/557f391ee4b07028ea60595b @itsnotjesse $$\color{blue}{\huge\tt{Nice~}}$$ $$\huge\mathcal{to~meet~}$$ $$\color{red}{\huge\tt{You~!}}$$
