Answer 1

Ответ:

извини за ужасный почерк

Answer 2

Ответ: -9 и - 8

Пояснение: Каждое из поизведений приравниваем к 0:

I. 2y+18=0

2y= - 18

y=-9;

II. 1,6-0,2y=0

0,2y= - 1,6

y= - 8

Answer 3

To solve the equation $(2y + 18)(1.6 - 0.2y) = 0$, we need to find the values of $y$ that make the equation true. This can be done by setting each factor equal to zero and solving for $y$:

1. Setting $2y + 18$ equal to zero: $2y + 18 = 0$ $2y = -18$ $y = -9$

2. Setting $1.6 - 0.2y$ equal to zero: $1.6 - 0.2y = 0$ $0.2y = 1.6$ $y = \frac{1.6}{0.2}$ $y = 8$

So, the solutions for $y$ are $y = -9$ and $y = 8$. These are the values that satisfy the equation $(2y + 18)(1.6 - 0.2y) = 0$.
