Answer:

x=7

Step-by-step explanation:

Collect like terms

2x=13+1.

D.K.G.S. and B are five points on line / • KG + GD = KD • SD + DB = SB KS + SG = KG What is the order of the points from left to

miskamm [114]

Answer: K,S,G,D,B

because KG + GD = KD => G is between K and D

SD + DB = SB => D is between S and B

KS + SG = KG => S is between K and G

=> The order of the points from left to right is K,S,G,D,B

Hailey paid $13 dollars for 1 3/7 kg of sliced salami.

quester [9]

Is the question how much it cost per kg?

If so, divide $13 by 1 3/7 kg.

13/(1 3/7) = 13/(10/7) = 13 * 7/10 = 91/10 = 9 1/10

Answer is 9 1/10 dollars per kg.
(Assuming I guessed your question correctly.)

Identify the vertical asymptotes of <img src="https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E3-16x%7D%7B-3x%5E2%2B3x%2B18%7D" id="TexForm

navik [9.2K]

$\sf \frac{ {x}^{3} - 16x}{ { - 3x}^{2} + 3x + 18 }$

To find the vertical asymptotes set denominator as 0

$\sf - 3x ^{2} + 3x + 18 = 0$

Divide both sides of the equation by-3

$\sf \: {x}^{2} - x - 6 = 0$

Write -x as a difference

$\sf \: {x}^{2} + 2x - 3x - 6= 0$

Factor out x from the expression

$\sf \: x \times (x + 2) - 3x - 6 = 0$

Factor out -3 from the expression

$\sf \: x \times (x + 2) - 3(x + 2) = 0$

Factor out x+2 from the expression

$\sf(x + 2)(x - 3) = 0$

When the product of factors equals 0, at least one factor is 0

$\sf \: x + 2 = 0 \\ \sf \: x - 3 = 0$

Solve the equations for x

$\sf \: x = - 2 \\ \sf \: x = 3$
