If we let x and y be the two numbers such that the difference of their squares will give 7, we have the equation,
                             x^2 - y^2 = (x + y)(x - y) =  7
From the given choices, the squares are 16 and 9 which are squares of 4 and 3, respectively. Therefore,
                              16 - 9 = (4 + 3)(4 - 3) = 7
Thus, the answer is letter A.

Answer:

(-4, -3)

Step-by-step explanation:

The graph of both lines will be shown below.

To find the solution, we need to find the point on the graph that both lines intersect on.

As we can see, both lines intersect on the point (-4, -3). Thus, that is the solution.

Best of Luck!

Solve the equation -5 = e/7
Papessa [141]
To solve equations, all we must do is isolate the variable and simplify. In this case, we need to get rid of the "/7" because it i with our "e." To do this, we should do the reverse operation of "/7" on both sides, and them simplify.

-5=e/7
*7   *7
-35=e

Using the math above, we can see that e=-35.
