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
The solution is x < 3.
Solution:
The given expression is 3x + 4 < 13.
To solve the given inequality.
3x + 4 < 13
Subtract 4 tiles on both sides of the inequality.
⇒ 3x + 4 – 4 < 13 – 4
⇒ 3x < 9
Divide by 3 tiles on both sides of the inequality.
⇒
⇒ x < 3
Hence the solution is x < 3.
