Question

Как делать? Алгебра 8 класс

Answer 1

5/х-1 = -3
ОДЗ: х≠1
5=-3(х-1)
5=-3х+3
3х=-2
х=-2/3.
√(х^2+8х+16)/(х-1)^2 = √(х+4)^2/(х-1)^2 = |х+4| / |х-1| = |-2/3+4| / |-2/3-1| = |3 1/3| / |-1 2/3| = 10/3 / 5/3 = 10•3/3•5 = 2

Answer 2

спасииибо

Answer 3

Ответ верный?

Answer 4

да

Answer 5

5/x-1=-3
ОДЗ: x≠1
5=-3x+3
3x=-2
x=-2/3
√(x^2+8x+16/(x1)^2=√(x+4)^2(x•1)^2=|x
+4|/|x-1|=|-2/3+4|/|-2/3-1|=13 1/3|/|-1
2/3|=10/3|5|3=10•3/3•5=2
