Answer:
Exterior Angle = 36 degrees
Step-by-step explanation:
<u><em>Each interior angle of a regular decagon measures 144 degrees.</em></u>
=> <u><em>We'll subtract 144 from 180 to get the measure of the exterior angle.</em></u>
=> Exterior Angle = 180-144
=> Exterior Angle = 36 degrees
Answer:
x=13
Step-by-step explanation:
Answer:
1. y-(is that a 7 or a 1?) = 2(x-4)
2. y-4 = (1/2)(x-2)
3. y = (2/3)(x+6)
... and so on
The formula for a line given point and slope is :
y - (y-value of point) = slope * x - (x-value of point)

Answer:
y=-1.7x+8
Step-by-step explanation:
An equation of a line is y=mx+c
m is the gradient and c is the y intercept, which is where the line intercepts y.
you work out m getting two points and then subtracting y - y ÷ x - x
So in this graph, if we chose points (6,-2) and (3,3) then we would do this equation.
So m = -1.7
c = 8 because it goes through 8 in y.
So the equation is y=-1.7x+8
