angle1 = 4y - 9°
angle2 = 40°
angle3 = 5y°
Angle sum property
180° = angle1 + angle2 + angle3
Therefore,
180 = (4y - 9) + 40 + 5y
180 = 4y - 9 + 40 + 5y
180 = 9y + 31
180 - 31 = 9y
149 = 9y
149/9 = y
What’s the question like what does it say
Answer:
the last graph
Step-by-step explanation:
The domain is the x values that make the function defined. We can see the entire shaded region starts at x = 0 and goes on to infinity. The lines are solid and not dotted, which indicates 0 is included. That’s why answer D has a bracket in-front of zero
