Answer:
Supplementary angles
x = 31
Step-by-step explanation:
Since, (3x + 25)° and 2x° are straight line angles. Therefore they are supplementary angles
(3x + 25)° + 2x° =180°
(5x + 25)° = 180°
5x + 25 = 180
5x = 180 - 25
5x = 155
x = 155/5
x = 31
Answer:
y = -2x - 3
Step-by-step explanation:
Answer:
b or c
Step-by-step explanation:
2×-1 +1= -1
-1>-3
2×0+1= 1
1>-3
For this reason the equality can be b or c
