Пошаговое объяснение:
1) y(m)=5.6-m
y(3) = 5.6-3 = 2.6
2)
0.3a^2 + 0.04b^2 + (0.16a^1-0.06b^2) =
=0.3a^2 + 0.04b^2 + 0.16a^1-0.06b^2= 0.46a^2 - 0.02 b^2
0.3a^2 + 0.04b^2 - (0.16a^1-0.06b^2) = 0.3a^2 + 0.04b^2 - 0.16a^1+0.06b^2=
=0.14a^2 + 0.1b^2
3)
(5a - 20b + 29c) - ( - 24a+29b - 24c ) = 5a - 20b + 29c + 24a-29b + 24c =
=29a-49b+53c
4)
( - 17x - 6.6y ) + ( 10y + 6.3x ) = 10y -6.6y +6.3x - 17x = -10.7x + 3.4 y
5)
y = -6 + 4a a = 9
y = -6 +4*9 = 30
y=30
