Answer #1
2x-p tem que ser igual a mx-1 , quando x for igual a 1. Assim,
2(1)-p=m(1)-1 ? 2-p=m-1 ? p+m=3
E, por sua vez, mx-1 tem que ser igual a (7x+4)/2 , quando x for igual a 6. Assim,
mx-1=(7x+4)/2 ? m(6)-1=(7(6)+4)/2 ? 6m-1=(42+4)/2 ?
? 6m-1=46/2 ? 6m-1=23 ? 6m=24 ? m=24/6 ? m=4
Ora, p+m=3 ? p+4=3 ? p=-1
Finalizando m-p=4-(-1)=4+1=5
