 Solve the system of inequalities and indicate all the integers which are in the solution set:
elena-s [515]
1.) a>10
2.) a<3.5
How I got it: 1.) Subtract 3 from both sides, leaving -2a<10.
2.) Divide by -2 from both sides, remember to flip the inequality sign when dealing with negatives. This leaves you with a>10.
For number 2.) I divided both sides by 5, leaving a<3.5, though this answer may be wrong.

Softa [21]

Answer:

f(2)= 11

                       f(2)= 3(2)^2+2(2)-5

                       f(2)= 11
