Answer:
True
Step-by-step explanation:
Each time a spinner is spun, there is an equal chance that each result will occur, thus each of these spins are independent.
Let x be the first angle
y be the second angle
z be the third angle.
for the second angle, complementary angles are angles sum are 90 degrees
y = 2 ( 90 - x )
y = 180 - 2x
2x + y = 180
for the third angle, supplementary angles are angles sum are 180 degrees
z = 0.5( 180 - x )
z = 90 - 0.5x
0.5x + z = 90
then the sum of a triangle is 180
x + y + z = 180
so x = 60
y = 60
z = 60
Answer:
the slope or gradient is 8/2=4
Answer: y= 1.5x-6
Step-by-step explanation:
1) Find the slope by using change in y over change in x: 
2) Then use the y intercept from the given: -6
3) create an equation in slope intercept form using those factors: y= 1.5x-6
