Ответ:

Объяснение:

6. (2a-9)/(1+a)

(2*(-5)-9)/(1+(-5))=(-10-9)/(1-5)=-19/(-4)=4 3/4=4,75

(2*(-4)-9)/(1+(-4))=(-8-9)/(1-4)=-17/(-3)=5 2/3

(2*(-3)-9)/(1+(-3))=(-6-9)/(1-3)=-15/(-2)=7 1/2=7,5

(2*0-9)/(1+0)=-9/1=-9

(2*0,5-9)/(1+0,5)=(1-9)/1,5=-8/1,5=-80/15=-16/3=-5 1/3

(2*1-9)/(1+1)=(2-9)/2=-7/2=-3 1/2=-3,5

(2*2,5-9)/(1+2,5)=(5-9)/3,5=-4/3,5=-40/35=-8/7=-1 1/7

(2*4-9)/(1+4)=(8-9)/5=-1/5=-0,2

(2*5-9)/(1+5)=(10-9)/6=1/6

(2*7-9)/(1+7)=(14-9)/8=5/8=0,625

7. (m²-n)/(3mn+2)

a) (4+1)/(3*(-2)*(-1)+2)=5/(6+2)=5/8=0,625

б) (-9-0)/(3*(-3)*0+2)=-9/2=-4 1/2=-4,5

в) (36-4)/(3*6*4+2)=32/(72+2)=32/74=16/37
