Answer:
The approximate solution of the system of equations is the point (-2.7,2.1)
Step-by-step explanation:
we have
-----> equation A
-----> equation B
Solve the system by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The solution is the point (-2.714,2.143)
see the attached figure
therefore
The approximate solution of the system of equations is the point (-2.7,2.1)
Answer:
40°
Step-by-step explanation:
Angle 1 and Angle 2 are corresponding angles.
Corresponding angles are congruent, so 3x + 4 = 5x - 20
Solving 3x + 4 = 5x - 20
3x = 5x - 24
2x = 24
x = 12
Substitute angle 1
3x + 4 = 36 + 4 = 40
Answer:
x = 4
x = -1
