an = a1 * r^(n-1)
a1 = first term = 1
r = common ratio = -3

so ur formula is : an = 1 * -3^(n-1)

Answer:

B. 3x^2 - 13x + 7

Step-by-step explanation:

6x^2 - 5x + 3 - (3x^2 + 8x - 4)

6x^2 - 5x + 3 - 3x^2 - 8x + 4

3x^2 - 13x + 7

The correct answer is the first option.

If you want to use elimination, you can sum the two equations for example, so that the x's simplify:

$(-2x+4y)+(2x+2y) = 16+8$

$6y = 24$

$y = 4$

Plug this value for y in one of the equations to derive the value of x:

$2x+2y=8 \implies 2x + 8 = 8 \implies x = 0$

So, the solution is $(x,y) = (0,4)$
