Using y=mx+b
m stands for slope, b stands for y-intercept
slope is rise/run, the y-intercept is the point where the line touches the y-axis
1- y=(4/6)x+(-2)
2- y=(-2)x+(3)
Answer:
The length of segment XY can be found by solving for a in

The measure of the central angle
is
.
Step-by-step explanation:
If the regular octagon has a perimeter of 122.4cm, then each side is 
The measure of each central angle is 
The angle between the apothem and the radius is 
The segment XY=a is the height of the right isosceles triangle.
We can use the Pythagoras Theorem with right triangle XYZ to get:


Therefore, the correct options are:
The length of segment XY can be found by solving for a in

The measure of the central angle
is
.
Answer:
Multiply both sides by the reciprocal 4
Step-by-step explanation:
You have to isolate the variable 'n' and to do so, you must multiply both sides by the reciprocal: 4.
-12 mutliplied by 4 is -36.
