The value of a baseball card can be represented by the equation Y - 3x+ 39, where x represents the number of year that Robert has owned the card and y represents the total value, in dollars, of the card. What was the value of the card when Robert originally purchased it?

$3
$13
$36
$39

9514 1404 393

  $39

Step-by-step explanation:

Assuming your equation is supposed to be ...

  y = 3x +39

The value of y when x = 0 is 39.

The value of the card when Robert purchased it was $39.

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

hope this !

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
