We can find x only if we know that the figure is a REGULAR octagon, i.e. an octagon with all sides equal, and all interior angles equal.
We will ASSUME that the figure is a regular octagon.
For a regular polygon, the central angle subtended by each side is equal.
The central angle is 360 degrees.
So the central angle subtended by a single side euqals
a=360 degrees / 8 sides = 45 degrees / side
Since x is the total angle subtended by three sides, so
x=3*45=135 °
You can see that the answers(y) of f(x) were Subtracted by a factor of 2 to make the answers(y) of g(x).
example: 9-2=7 81-2=79
when a number is added to or subtracted from a function the graph will make a horizonal or vertical shift. therefore C. is correct
Answer:
25:3
Step-by-step explanation:
50 / 6 is simplified to 25 / 3 which would equal 25 : 3.
Answer:
The y intercept is (0,13)
The equation of the line is y = -2x+13
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
y = -2x+b
Substituting the point
3 = -2(5) +b
3 = -10 +b
Add 10 to each side
13 =b
The y intercept is (0,13)
The equation of the line is y = -2x+13
