Answer:
The solution is the point (1,-4)
Step-by-step explanation:
we have
----> equation A
----> equation B
we know that
The solution of the system of equations by graphing is the intersection point both graphs
using a graphing tool
The intersection point is (1,-4)
see the attached figure
therefore
6(9)-8(-2)
6*9=54
8*(-2)=-16
54-16=38
38<-----
I think the answer is the first one and the last one .
the relationship between <4 and <7 is they are vertical angles
