Identify the solution and graph of the given inequality. 34 > 3(2 − x)
zloy xaker [14]

Answer:

x > 28/3

Step-by-step explanation:

34 > 3(2 − x)

simplify the bracket

34 > 6 -3x

combine the like terms

34 - 6 > 3x

28 > 3x

divide by 3

x > 28/3

Sorry I don't know how to graph here, but I can graph it by writing the way it can be graphed.

It is in slope intercept form; y = mx + b

where mx is the slope and b is the y-intercept;

x>28/3; where 28/3 is the slope which means; at the y-intercept, go up 28 times and to the right 3 times

And b is 0; which means at 0 where the slope will be applied, go up 28 times and to the right 3 times.

Hope this helps!

Good luck.
