Which graph shows a reflection across the x-axis from the orange figure to the blue figure? A. ?
B. ?
C. ? <---

C.

Step-by-step explanation:

When a shape is reflected on the x-axis it's y-coordinates switch signs. For example point A (-5,3) switches to A' by turning into (-5,3). And for a reflection on the y-axis it would be the opposite, the x-coordinates would switch signs.

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200
