Supplementary angles add up to 180°
-> The measure of an angle that is supplementary to a 71° angle is 180° - 71° = 129°
Answer:
The correct answer would be 3:5
Step-by-step explanation:
It is asking about the second half to the total number of points scored.
first half : 9
second half : 15
9:15 = 3:5
Answer:
Not sure if you mean 2x+y=-4 or 2x+y=4
either way put it in y=mx + b form (slope intercept)
Step-by-step explanation:
so for 2x+y = -4 first move everything away from the side with "y" by -2x from each side you get y= -2x+ -4 so m= -2/1 (slope) and b= -4 the place the line crosses the y axis
so for 2x+y = 4 first move everything away from the side with "y" by -2x from each side you get y= -2x+ 4 so m= -2/1 (slope) and b= 4 the place the line crosses the y axis
