Step-by-step explanation:
The coefficients of the y terms are -3 and 2. The least common multiple of 3 and 2 is 6. So multiply the first equation by 2 and the second equation by 3, so that the y terms have a coefficient of 6.
4x − 6y = 42
-18x + 6y = 21
The signs are opposite, so add the equations together.
-14x = 63
x = -9/2
Answer:
y = -3x -2
Step-by-step explanation:
parallel lines have same slope
line d: slope (m) = -3
y intercept (b) = -2
equation y = mx + b y = -3x -2
Answer:
5π/3 radians
Step-by-step explanation:
The central angle for arc CBD has the same measure as the arc:
300° = 5π/3 radians
_____
180° is π radians, so (5/3)(180°) = 300° = (5/3)π radians.
