If
f x x ( ) 4 2  
, then
f x( 1)  =

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51

step-by-step explanation:

i need a diagram

step-by-step explanation:

no

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5
