It's an identity if it has infinite solutions and everything is right, which would mean that if both sides of the equation are equal after eliminating the variable then the variable does not matter and it will always be equal. If it is not equal after eliminating the variable then that means that no matter what the variable is, it does not matter and the equation will have no solution
Answer:
A
Step-by-step explanation:
We take a look at this expression:
and notice that both terms are square numbers.
and
.
There is a specific formula that I highly recommend you memorize involving differences of squares. It states that given the difference of squares
, it can always be factored into
.
Here, we can apply that. In this case, a = 7x and b = 3. So:

Thus, the answer is A.
Hope this helps!
Answer:
Using the slope-intercept form, the slope is 4 .
There is no graph or equation for me to solve :(
