X/15 = 10/20
20x = 150
x = 150/20
x = 7.5
Answer:
2x= 3x-7
-x=-7
x=7
so, the first option

Answer:
Hannah is wrong. The correct answer is 1/3.

Answer:
.
Step-by-step explanation:
DC = 16 and
DB = 30 so
CB = 14
DB = 30 and
EB = 49 so
EB = 19
Symmetrical functions can be about the x and y axis. Essentially, if we reflect the graph across the y or x axis, we get the same graph. Some other graphs can be reflected across both the x and y axis at the same time and be symmetrical. These can be classified as odd and even functions. You can test this by replacing x and y with -x and -y and simplify the equation. If the results comes out to be the same as the original, it is symmetrical across the origin.
Best of Luck!
