Respuesta:

Por lo tanto, los valores de y correspondientes son 3, 2, 4 y 8

Explicación paso a paso:

Dada la función f (x) = -5x + 3

Cuando x = 0

f (0) = -5 (0) + 3

f (0) = 0 + 3

f (0) = 3

Cuando x = 1/5

f (1/5) = -5 (1/5) + 3

f (1/5) = -1 + 3

f (1/5) = 2

Cuando x = -1/5

f (-1/5) = -5 (-1/5) + 3

f (-1/5) = 1 + 3

f (-1/5) = 4

Cuando x = -1

f (-1) = -5 (-1) + 3

f (-1) = 5 + 3

f (-1) = 8

Umnica [9.8K]

Answer:

  • ribbon: $0.45
  • markers: $0.08

Step-by-step explanation:

Each purchase will be the sum of products of item price and number of items. The two purchases give rise to two equations.

__

<h3>equations</h3>

The variables are defined in the problem statement. The two purchases are ...

  11r +16m = 6.23

  13r +7m = 6.41

__

<h3>solution</h3>

A calculator offers a simple way to find the solutions to these equations. The attachments show the solution to be ...

  • r = 0.48
  • m = 0.08

The cost of ribbon is $0.45; the cost of a marker is $0.08.

__

The "cross-multiplication" method of solving these equations seems particularly useful when the coefficients are mutually prime. It starts with a rewrite to general form:

  • 11r +16m -6.23 = 0
  • 13r +7m -6.41 = 0

Then we define three "cross products":

Δ1 = (11)(7) -(13)(16) = -131

Δ2 = (16)(-6.41) -(7)(-623) = -58.95

Δ3 = (-6.23)(13) -(-6.41)(11) = -10.48

The solutions are ...

  r = Δ2/Δ1 = -58.95/-131 = 0.45

  m = Δ3/Δ1 = -10.48/-131 = 0.08

The cost of ribbon is $0.45; the cost of a marker is $0.08.
