Answer:
Both -6x +7>-5 and 14x-2<12
Step-by-step explanation:
Your question said "Which of the FOLLOWING inequalities require the inequality symbol to be reversed when solving" I hope this means multiple choice because i got both 14x-2<12 and -6x +7>-5 to be reversed when i finished solving them. For 6x +7>-5 I got X < 2, and for 14x-2<12 I got X > -28, therefore those two are correct.

»f(x) = 7x² - 3x + 7
»f(2) = 7(2)² - 3(2) + 7
»f(2) = 7(4) - 6 + 7
»f(2) = 28 - 6 + 7
»f(2) = 29
»f(-1) = 7(-1)² - 3(-1) + 7
»f(-1) = 7(1) + 3 + 7
»f(-1) = 7 + 3 + 7
»f(-1) = 17
»f(0) = 7(0)² - 3(0) + 7
»f(0) = 7(0) - 0 + 7
»f(0) = 0 - 0 + 7
»f(0) = 7
so, f(2) + f(-1) + f(0) is
7r=-7/2
divide both sides by 7 to get r by itself
(7r)/(7) = (-7/2)/(7)
if you don't quite see it, think of multiplying both sides by 1/7 instead (its the same thing as dividing by 7)
(7r)*(1/7)=(-7/2)*(1/7)
r=-1/2
