Preciso de ajuda por favor

Answer 1

◇1__________________

x=10 , y=5

x+y | 10+5 = 15

x-y | 10-5 = 5

y-x | 5-10 = -5

x.y | 10.5 = 50

x÷y | 10÷5 = 2

◇2_________________

x=7 , y=-7

x+y | 7 + (-7) = 0

x-y | 7 -(-7) = 7+7 = 14

y-x | -7 -(+7) = -7-7= -14

x.y | -7.7= -49

x÷y | 7÷-7 = -1

◇3_________________

x=-2 , y=-1

x+y | -2-1 = -3

x-y | -2 -(-1) = -2+1 = -1

y-x | -1 -(-2) = -1+2 = 1

x.y | -2.-1 = 2

x÷y | -2÷-1 = 2

◇4_________________

x=-25 , y=5

x+y | -25+5 = -20

x-y | -25-5 = -30

y-x | 5-(-25)=5+25=30

x.y | 25.5 = 125

x÷y | -25÷5 = -5

◇5_________________

x=-30 , y=30

x+y | -30+30= 0

x-y | -30-30 = -60

y-x | 30-(-30) = 60

x.y | 30.30 =-900

x÷y | 30÷(-30) = -1

espero ter ajudado :)

♧ boa sorte na prova ♧
