Answer:
Step-by-step explanation:
-5(x + 7) < -10 <em>use the distributive property </em><em>a(b + c) = ab + ac</em>
(-5)(x) + (-5)(7) < -10
-5x - 35 < -10 <em>add 35 to both sides</em>
-5x < 25 <em>change the signs</em>
5x > - 25 <em>divide both sides by 5</em>
x > -5
9
f(-3)=-1/3=-3 then crisscross
-3*3=-1
-9=-1 divide by -1
f(-3)=9
1.2
1.2 is answer but you can simplify to 1 1/5
