Answer : option A
16<=2(3x-1) and 2(3x-1)<28
Phyllis solved the compound inequality. She began by first breaking the inequality into two separate inequalities. Then she correctly solved each for x
3<=x and x<5
x>=3 and x<5
Now we graph the solution
x>=3, we have = sign so we use closed circle at 3.
Then for greater than symbol we shade to the right
For x<5, there is no = sign so we use open circle at 5
for < than symbol we shade to the left
For x>=3 and x<5, we take the intersection of both graphs
So option A is the answer.
