Answer:
Step-by-step explanation:
step 1
Find the equation of the solid line
From the graph take the points (0,3) and (4,11)
Find the slope
The equation of the solid line in slope intercept form is equal to
we have
----> the y-intercept is the point (0,3)
substitute
therefore
The inequality is
step 2
Find the equation of the dashed line
The slope is given
From the graph take the y-intercept (0,-5)
The equation of the solid line in slope intercept form is equal to
we have
substitute
therefore
The inequality is
because the shaded region is below the dashed line
therefore
The system of inequalities is
Answer:
right
neither
straight
neither
Step-by-step explanation:
The first angle is a right angle. The box in the corner indicates a 90 degree angle
The second angle is less than 90 degrees so it is an acute angle
The third angle is a straight line so it is a straight angle.
The fourth angle is wider than 90 degrees it is an obtuse angle
