Answer: Yes, the point (3,4) is a solution to the system.
===================================================
Proof of this:
Replace x with 3 and y with 4 in the first equation
x+y = 7
3+4 = 7
7 = 7
This confirms the first equation. Repeat for the second equation
x-2y = -5
3-2(4) = -5
3 - 8 = -5
-5 = -5
We get true equations for both when we plug in (x,y) = (3,4). This confirms it is a valid solution to the system of equations. It turns out it's the only solution to this system of equations. Visually, the two lines cross at the single location (3,4).
Answer:

Answer:
< W ≅ < P.
Step-by-step explanation:
< W ≅ < P.
< W is the refection of < P over the x-axis.
Step-by-step explanation:
(3x2 - 2x - 4) (2x2 + x - 3)
6x4 + 3x3 - 9x2 - 4x3 - 2x2 + 6x - 8x2 - 4x + 12
Solving like terms
6x4 - x3 - 19x2 + 2x + 12
