The graph below shows four straight lines, w, x, y, and z: graph of line w going through ordered pairs negative 4, negative 2 and negative 1, 5. graph of line x going through ordered pairs negative 2, negative 1 and 0, 5. graph of line y going through ordered pairs negative 1, negative 3 and 1, 3. graph of line z going through ordered pairs 0, negative 5 and 2, 1. which line is represented by the function f(x) = 3x + 5?
line w
line x
line y
line z

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

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
