Think of the given points as endpoints of vectors.

The point (3, 1) is the terminus of the vector 3 i + j.

The point (-4, 2) is the terminus of -4 i + 2 j.

By the "triangle rule" for vector summation, the vector starting at (3, 1) and ending at (-4, 2) is the difference between these two vectors.

(-4 i + 2j) - (3i + j) = -7 i + j

Which sum is equal to
Semmy [17]

Answer:

Correct choice is A

Step-by-step explanation:

Note that the denominator x^2-25=(x-5)(x+5). Then rewrite the numerator x^2+6x-5 as x^2+5x+x-5=x(x+5)+(x-5).

Substitute both expression into the initial expression:

\dfrac{x^2+6x-5}{x^2-25}=\dfrac{x(x+5)+(x-5)}{(x+5)(x-5)}=\dfrac{x(x+5)}{(x+5)(x-5)}+\dfrac{(x-5)}{(x+5)(x-5)}=\dfrac{x}{x-5}+\dfrac{1}{x+5}.

Subtracting 3x form both sides

2x - 20 = 18

adding 20 to both sides

2x = 38

dividing both sides by 2

x = 19
