IF=2x+2, IZ=2x+12 solve for x
Digiron [165]
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.

What are the solutions of the equation x4−10x2+9=0? Use u substitution.
PSYCHO15rus [73]

Answer:

Step-by-step explanation:

X^4 - 10X^2 + 9 =0    This factors. It just looks odd.

(x^2 - 1)(x^2 - 9) = 0

x^2 - 1 = (x + 1)(x - 1) = 0

x = 1 and x = - 1

x^2 - 9 = (x + 3)(x - 3) = 0

x = 3

x = -3

The correct answer is C (third one down).

If y=2 find the the value of y+6
Tems11 [23]

If y = 2, to find the value of y + 6, we need to substitute the value of y (2) into the expression y + 6. Substituting 2 for y, we get the equation 2 + 6. Since 2 + 6 = 8, that means that substituting y = 2 into the expression y + 6, we get 8.
