substitute
Remember that
Everything to the left of the solid line is shaded
so
The inequality is
step 2
<em>Find the equation of the second inequality</em>
Find the equation of the second dashed line
we have the ordered pairs
(0,2) and (4,0)
<u><em>Find the slope</em></u>
The formula to calculate the slope between two points is equal to
substitute the values
The equation in slope intercept form is equal to
we have
---> the y-intercept is given
substitute
Remember that
Everything below and to the left of the line is shaded
so
The inequality is
Rewrite
Multiply by 2 both sides
therefore
The system of inequalities is

Answer:
x = 1/3 or x = -2/3
Step-by-step explanation:
Let's solve your equation step-by-step.
9x2+3x−2=0
For this equation: a=9, b=3, c=-2
9x2+3x+−2=0
Step 1: Use quadratic formula with a=9, b=3, c=-2.
x = 1/3 or x = -2/3
