Identify the graph and describe the solution set of this system of inequalities. Y<-3x-2 y>-3x+8
1 answer:
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
y < -3x-2 -----> inequality A
The solution of the inequality A is the shaded area below the dashed line y=-3x-2
The slope of the dashed line is negative m=-3
The-y-intercept of the dashed line is (0,-2)
The x-intercept of the dashed line is (-0.67,0)
y > -3x+8 -----> inequality B
The solution of the inequality B is the shaded area above the dashed line y=-3x+8
The slope of the dashed line is negative m=-3
The-y-intercept of the dashed line is (0,8)
The x-intercept of the dashed line is (2.67,0)
using a graphing tool
The system of inequalities y < -3x-2 and y > -3x+8 has no solution (parallel lines)

Step-by-step explanation:
Given that a homeowner is three times as likely to purchase additional jewelry coverage as additional electronics coverage
If probability of purchasing additional electronics coverage = p, then prob of purchasing jewelry coverage = 3p
The two events are independent hence joint probability is product of these two.
i.e. P(both) =
This is given as 0.2
the probability that a homeowner purchases exactly one coverage.
= Prob he purchases I + prob he purchases II-2(prob he purchases both)
