2 answers:
The formula 
means that from statement q implies statement p.
When statements p="two linear functions have different coefficients of x" and q="the graphs of two functions intersect at exactly one point", then the statement have a form: "If the graphs of two functions intersect at exactly one point, then two linear functions have different coefficients of x."
When statements p="two linear functions have different coefficients of x" and q="the graphs of two functions intersect at exactly one point", then the statement

Answer:
B
Step-by-step explanation:
We can see in the expression that there are 2 x² blocks, 4 -x blocks, and 3 -1 blocks. Therefore, we can write this as
2 * x² + 4 * (-x) + 3 * (-1) = 2x²-4x-3
Comparing this with each answer, we have
A: x²-2x-4 + x² + 2x-1 = 2x²-5. This is not correct
B: 3x²-7x+1-(x²-3x+4) = 3x²-7x+1 -x²+3x-4 = 2x²-4x-3. This seems correct but we can check the other answers to be sure
C: (2x+1)(x-3) = 2x²-6x+x-3 = 2x²-5x-3. This is incorrect
D: . This is incorrect
