Someone and correct me if im wrong and explain all of it if i am : ) 25pts
which numbers are solutions to the inequality x < −7, using the replacement set {−15, −10.5, −7.2, −7, 0}?
choose all answers that are correct. i think its b-c-and d
a.
–7
b.
−7.2
c.
−10.5
d.
−15
solve. i think its a
8y – 24 > –16
a.
y > –5
b.
y > –1
c.
y > 1
d.
y > 5
the solution to which inequality is shown
> (-)< (7s the number outlined) i think its a
a.
y + 5 > –2
b.
y + 5 ≥ –2
c.
y + 5 < –2
d.
y + 5 ≤ –2
solve.
solve i think its d
- t/5 ≥15
a
t ≤ –75
b.
t ≥ –75
c.
t ≤ –3
d.
t ≥ –3

*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.
