*Yes, B, C, and D are correct. -15, -10.5, and -7.5 are solutions to x<-7*........................... ...................................................................................................................................... *8y – 24 > –16............................................................................................................. 8y>8 ADD 24 to both sides ....................................................................................... y>1 so C. divide both sides by 8................................................................................. It is not A because the opposite of subtracting 24 is adding 24. So you add 24 to both sides to undo the subtraction. -16+24=8 Then you divide both sides by 8, which gives you y>1. I think you probably subtracted 24 from -16 instead of adding it.*......................................... ...................................................................................................................................... *I'm not sure what to make of the third one, is that a number line or...?*............................... ...................................................................................................................................... *- t/5 ≥15 ........................................................................................................................ -t ≥ 75 MULTIPLY both sides by 5.................................................................................... t ≤ -75 divide both sides by -1, and flip the sign, because when dividing an inequality by a negative number you must flip the sign.............................................................................. So A would be correct. .................................................................................................... I believe if you divided the 15 by 5 and didn't flip the sign you would get D.*......................... Also, sorry, my enter key isn't working right, so it's all scrunched together.

IrinaVladis [17]

From the Venn diagram: 15 players like Chemstrand, 17 players like Chemgrass, 13 players like both Chemstrand and Chemgrass while 10 players like neither Chemstrand nor Chemgrass.

The missing values in the frequency table are x - representing the number of players that like both Chemstrand and Chemgrass, y - representing the number of players that like Chemgrass but do not like Chemstrand and z - representing the number of players likes Chemstrand but do not like Chemgrass.

The number of players that like both Chemstrand and Chemgrass is 13. The number of players that like Chemgrass but do not like Chemstrand is 17. The number of players likes Chemstrand but do not like Chemgrass is 15.

Therefore, x = 13, y = 17 and z = 15

Need help please :( What is the second term of (s+v)^5?

Citrus2011 [14]

First compute the coefficient like this:
$C_5^1=\frac{5!}{1!(5-1)!}=\frac{5!}{4!}=\frac{5\times4!}{4!}$
Simplifying the fraction over 4! we get:
$C_5^1=5$
and the variables are $s^4v$ . So answer $5s^4v$ .

The correct answer is C then.
