Answer: $20

Explanation: First ask yourself how many groups of 5 can go into 12: 2. If Denise sells 2 groups of 5 then there will be 2 flowers left over, but Denise does not sell flowers in groups of 2. If Denise sells 1 group of 5 then there will be 7 flowers left over, which is still not divisible by three. Therefore, Denise must sell 4 groups of 3 for there to be 12 flowers. $5 x 4 = $20

J'K'L'M' is a translation of JKLM by vector (-6/2). What are the coordinates of K'? What are the coordinates of M'?
pochemuha

By applying the concept of <em>rigid</em> transformation and the equation of translation we conclude that the coordinates of points K' and M' are (-2, 3) and (-4, 1).

<h3>How to apply a translation to a point on a Cartesian plane</h3>

<em>Rigid</em> transformations are transformations applied onto <em>geometric</em> loci such that Euclidean distance is conserved at every point of the loci. Translations are an example of <em>rigid</em> transformations, whose formula is defined by the following expression:

P'(x, y) = P(x, y) + \vec v     (1)

Where:

  • P(x, y) - Original point
  • P'(x, y) - Resulting point
  • \vec v - Translation vector

If we know that K(x, y) = (4, 1), M(x, y) = (2, -1) and \vec v = (-6, 2), then the coordinates of points K' and M' are:

Point K'

K'(x, y) = (4, 1) + (-6, 2)

K'(x, y) = (-2, 3)

Point M'

M'(x, y) = (2, -1) + (-6, 2)

M'(x, y) = (-4, 1)

By applying the concept of <em>rigid</em> transformation and the equation of translation we conclude that the coordinates of points K' and M' are (-2, 3) and (-4, 1).

The solution to 2x2 – 11 = 87 is
frozen [14]

\text{Solve the equation:}\\\\2x^2-11=87\\\\\text{Add 11 to both sides}\\\\2x^2=98\\\\\text{Divide both sides by 2}\\\\x^2=49\\\\\text{Square root:}\\\\x=\pm\sqrt49\\\\\text{This means that the answer could be 7 or -7}\\\\\boxed{\text{x=7 or x= -7}}
