Answer:
Part 1) The solution is the point (-2,0)
Part 2) The solutions are the points (-2,0) and (0,2)
Step-by-step explanation:
Part 1
we have
-----> equation A
----> 
---> equation B
Solve the system by graphing
Remember that the solution of the system is the intersection point both graphs
using a graphing tool
The solution is the point (-2,0)
see the attached figure N 1
Part 2
we have
-----> equation A
----> equation B
Solve the system by graphing
Remember that the solution of the system are the intersection points both graphs
using a graphing tool
The solutions are the points (-2,0) and (0,2)
see the attached figure N 2

Answer:
z = 
or z = 195.8
y=-30
a = 5
b = -7
x = 64
Step-by-step explanation:
Fun, geometry disguised as probability.
That's a pentagon, which we can view as 10 right triangles with legs a and s/2 (half of s) and hypotenuse r. So area of the pentagon is
P = 10 × (1/2) a (s/2) = 10 (1/2) (3.2) (4.7/2) = 37.6
The area of the circle is πr² so the circle area is
C = π (4²) = 50.265482
The white area is the difference, C-P, and the probability we seek is the fraction of the circle that's white, so (C-P)/C.
p = (C-P)/C =1-P/C = 1-37.6/50.265482 = 0.251971
Answer: 0.25
Higher than I would have guessed from the figure.
Answer:
Step-by-step explanation:
If you're talking about a square, then the area would be 40.
If you're talking about a triangle, then the area would be 20.
