Question

Y=0,2x A)Y если x=-5, 0, 5 Б) x если y=-2, 0, 2

Answer 1

Ответ:

а)

y(-5) = 0,2 · (-5) = -1

y(0) = 0,2 · 0 = 0

y(5) = 0,2 · 5 = 1

б)

-2 = 0,2x

0,2x = -2 | : 0,2

0,2x : 0,2 = -2 : 0,2

x = -10

0 = 0,2x

0,2x = 0

x = 0

2 = 0,2x

0,2x = 2 | : 0,2

0,2x : 0,2 = 2 : 0,2

x = 10

Answer 2

To find the values of Y when given different values of X and the values of X when given different values of Y, you can use the equation Y = 0.2x. Let's calculate the values:

A) Y when X = -5, 0, 5:

1. When x = -5: Y = 0.2 * (-5) = -1

2. When x = 0: Y = 0.2 * 0 = 0

3. When x = 5: Y = 0.2 * 5 = 1

So, the values of Y when x is -5, 0, and 5 are -1, 0, and 1, respectively.

B) X when Y = -2, 0, 2:

1. When Y = -2: -2 = 0.2x To find x, divide both sides by 0.2: x = -2 / 0.2 = -10

2. When Y = 0: 0 = 0.2x x = 0 / 0.2 = 0

3. When Y = 2: 2 = 0.2x x = 2 / 0.2 = 10

So, the values of X when Y is -2, 0, and 2 are -10, 0, and 10, respectively.
