Answer:
Since the question is indicating to use a graphing calculator, we can assume that we would be required to graph both of the equations.
Red = 
Blue = 
By graphing those equations, we can determine the solution(s)
The points where the graphs intersect would be your coordinates to derive your solution
Red = (1.864, 1.966)
Blue = (-0.427, 1.254)
The solutions would be the x-value of the ordered pair, in this case,
x = 1.864 AND x = -0.427
Answer:
B.
Step-by-step explanation:
Well, you want to solve for a. You first add the 4 to both sides.
3a-4<5
3a<9
Then you want to get a by itself so you divide both sides by 3. Since the 3 is positive you don't have to worry about switching the sign. It stays this way <
After you divided both sides by 3 you get a<3
