A reflection over the x-axis

Step-by-step explanation:

      If you were to put a mirror up to the x-axis and look at one of the shapes, you would "see the" other so we can conclude this is a reflection over the x-axis.

In other words, you could "fold" the graph in half over the x-axis and the two figures would line up.

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200
