Question

Пожалуйста, любое задание какое сможете, умоляю​

Answer 1

1) г

2) в

3) x(x - y)/xy = x-y/y

4) b $\neq$ -1

5) (m-10)(m+10)/3(m-10) = m+10/3

6) (3a - 1)^2/(-5*(3a-1)) = -(3a - 1)/5

a = 4 1/3, -(3a - 1)/5 = - (3 * 4 1/3 - 1 )/ 5 = - (13 - 1)/5 = -12/5 = -2,4

7) (4x^2 + 3x - 1)/(16x^2 - 1) = 4(x-0,25)(x+1)/(4x - 1)(4x + 1) = (x + 1) / (4x + 1)

8) 3(x-y) - 2x(x-y) / (x-y)(x+y) = (x-y)(3-2x) / (x-y)(x+y) = 3-2x / x+y

9) x^2 - y^2 + 5(x-y) / x^2 - y^2 - 5(x-y) = (x-y)(x+y) + 5(x-y) /  (x-y)(x+y) - 5(x-y) = (x-y)(x+y+5)/(x-y)(x+y-5) = x+y+5/x+y-5

10) Построй график x^2 -4x + 3, я думаю этому вас научили
