Lucía makes braided key chains out of cotton cord. For every 8 feet of cotton cord she has, she can make 3 braided key chains. P
asambeis [7]

Lucía needs 13.33 feet of cotton.

Since Lucía makes braided key chains out of cotton cord, and for every 8 feet of cotton cord she has, she can make 3 braided key chains, to represent the relationship between the feet of cotton cord and the number of key chains and find the number of feet of cotton cord Lucia needs to make 5 key chains, the following calculations must be performed, through a cross multiplication:

  • 8CC = 3KC
  • 3 = 8
  • 5 = X
  • 5 x 8/3 = X
  • 40/3 = X
  • 13.33 = X

Therefore, Lucía needs 13.33 feet of cotton.

Find the equation of the line of symmetry of y= (x+2)(x-8).​
Daniel [21]

Answer:

line of symmetry , x = 3

Step-by-step explanation:

Standard form of quadratic equation  is y = ax^2 + bx + c, where a, b, and c equal all real numbers. You can use the formula x = -b / 2a to find the line of symmetry.

y = (x+ 2)(x-8)\\\\y = (x^2 -8x + 2x -16)\\\\y = x^2 -6x -16

a = 1, b = -6, c = -16

Line of symmetry is ,

                           x = -\frac{b}{2a} = -\frac{-6}{2}  = 3
