Question

| -0.42 | = | y | * | - 2.8 |

Answer 1

| -0.42 | = 0.42

| - 2.8 | =2.8

0.42=  2.8| y |

 | y | =0.42/2.8= 0.15

у=-0.15

у=0.15 

 

Answer 2

Расскрываем скобки.

-0,42=-2,8у

-2,8у=-0,42

у=-0,42/(-2,8)

у=0,42/2,8

у=0,15

Ответ:у=0,15

 

Answer 3

To solve for y in the equation:

| -0.42 | = | y | * | - 2.8 |

We start by simplifying each absolute value term:

| -0.42 | = 0.42 | -2.8 | = 2.8

Substituting these values back into the original equation, we have:

0.42 = | y | * 2.8

To solve for | y | , we divide both sides by 2.8:

0.42 / 2.8 = | y |

0.15 = | y |

So | y | = 0.15.

However, since absolute value represents distance, y can be either positive or negative. Therefore, there are two solutions:

y = 0.15 or y = -0.15
