Question

Can someone help me?? and show the steps on how u got the answer

Answer 1

-1 - 10a < -1    or      10 + 3a ≤ -5

+1            +1         -10           -10

   -10a < 0     or             3a ≤ -15

   $\frac{-10a}{-10} > \frac{0}{-10}$     or         $\frac{3a}{3} \leq \frac{-15}{3}$

       a > 0      or          a ≤ -5  

notice the left inequality symbol flipped because we divided by a negative

             -5 ≥ a > 0

Graph: -5 -------------o 0   (dot is filled at -5 and not filled at 0)

Answer 2

-1-10a<-1 or 10+3a≤ -5

-10a<0 or 3a≤-15

a>0 or a≤-5
