Answer: (-2, 1), (-4, -3)

Step-by-step explanation:

y = x² + 8x + 13

y = 2x+5

x² + 8x + 13 = 2x+5

x² + 6x + 13 = 5

x² + 6x + 8 = 0

x² + 2x + 4x + 8 = 0

(x+2)(x+4)=0

<u>x=-2 or x=-4</u>

y=2(-2)+5

y=-4+5

<u>y=1</u>

y=2(-4)+5

y=-8+5

<u>y=-3</u>

ANSWER

The value of x is

9


EXPLANATION

F is the point of intersection of the medians of the triangle,

The ratio is

IF:IZ=2:3


This implies that,

(2x + 2): (2x + 12) = 2: 3


We can write this as a fraction to get,

\frac{2x + 2}{2x + 12}  =  \frac{2}{3}


We cross multiply to get,

3(2x  + 2) = 2(2x + 12)

Let us expand the brackets yo obtain,

6x + 6 = 4x + 24


We group like terms to get,

6x - 4x = 24 - 6


2x = 18


We divide both sides by 2 to get,

x = 9

The correct answer is B.
