Since IK is the sum of Lines JK and IJ, we set IK = JK + IJ.
9x-19 = 5x+12 + x-4
Combining like terms,
9x-19 = 6x+8
adding 19 and subtracting 6x,
3x = 27
dividing by 3,
x = 9
Plugging in x for JK, IK, and IJ:
JK = 5*9 + 12
= 45 + 12
=57

IK = 9*9-19
=81-19
=62

IJ = 9-4
= 5

Since IJ is 5, JK is 57, and IK is 62, the answer is B.

The whole line is IK.
This means that IJ + JK = IK

IJ = x - 4
IK = 9x - 19
JK = 5x + 12

(x - 4) + (5x + 12) = 9x - 19
6x + 8 = 9x - 19
8 = 3x - 19
27 = 3x
9 = x

Now that you have x, insert it into each of the segments.
IJ = x - 4
IJ = 9 - 4
IJ = 5

IK = 9x - 19
IK = 9(9) - 19
IK = 81 - 19
IK = 62

JK = 5x + 12
JK = 5(9) + 12
JK = 45 + 12
JK = 57

So the answer would be:
B. IJ = 5, JK = 57, IK = 62

Answer:

Option 2 is correct that is $\frac{x+2}{x+9}$ and $x\neq-9$ and $x\neq-12$

Step-by-step explanation:

We have been given with the expression $\frac{x^2-10x-24}{x^2-3x-108}$

We will simplify the given expression by factorisation we will get $\frac{x^2-12x+2x-24}{x^2-12x+9x-108}$

Taking x as common from first two terms in numerator and 2 from last two terms in numerator

Similarly, take x common from first two terms and 9 from last two terms in denominator we will get

$\frac{x(x-12)+2(x-12)}{x(x-12)+9(x-12)}$

After arranging the terms we will get $\frac{(x+2)(x-12)}{(x+9)(x-12)}$

Taking out the common factor which is (x-12) from numerator and denominator it will get cancelled we will get

$\frac{(x+2)}{(x+9)}$

Hence, Option 2 is correct that is $\frac{x+2}{x+9}$ and $x\neq-9$ and $x\neq-12$

How do I solve x(3x-17)=0 using the square root property

scZoUnD [109]

Answer:

x = 0 or $x = \frac{17}{3}$

Step-by-step explanation:

We have the quadratic equation of variable x and we have to solve the equation using the square root property.

Now, we have x(3x - 17) = 0

⇒ 3x² - 17x = 0

⇒ $3(x^{2} - \frac{17}{3}x ) = 0$

⇒ $x^{2} - 2 \times (\frac{17}{6}) \times x + (\frac{17}{6} )^{2} = (\frac{17}{6} )^{2}$

⇒ $(x - \frac{17}{6})^{2} = (\frac{17}{6} )^{2}$

Now,square rooting both sides we get,

$x - \frac{17}{6} = \pm\frac{17}{6}$

Therefore, either x = 0 or $x = \frac{17}{3}$ (Answer)

Given the following system of equations: −x + y = 2 2x + 4y = 32 What action was completed to create this new equivalent system

tiny-mole [99]

Answer:

you just need to devide by 2 the second equation

Step-by-step explanation:

-x + y = 2 (you leave it as it is)

2x + 4y =32 => 2x/2 +4y/2 = 32/2

=> x + 2y =16

we can devide or multiply in an equation by any number we want, as long as we do it to every term.
