Answer:
Step-by-step explanation:
we have
----> equation A
-----> equation B
----> equation C
adds equation A and equation C
-----> equation D
adds equation B and equation C
-----> equation E
we have the system
-----> equation D
-----> equation E
Multiply equation E by -1.5 both sides
-----> equation F
adds equation D and equation F
<em>Find the value of z</em>
substitute the value of y in equation E (or substitute in equation D)
<em>Find the value of x</em>
substitute the value of y and z in equation A (or equation B or C)
therefore
The solution of the system of equations is
Answer:
C. Line PQ
Step-by-step explanation:
Tangent means touching, not crossing.
Look at your report card it should be on there somewhere
