Evaluate f(x) = 5x – 8 when 8 when I = -3.0, and 4.​

f(3)=3

Step-by-step explanation:

Plugin 3 for x, and simplify

f(x) =5(x)−12

f(3) =5(3)−12

=15−12

f(3)=3

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
