Question

2) y = 0,01x - 2,5, если х = 25; 250; 2,5;

Answer 1

y = 0,01x - 2,5

Ответ:

1. y(25) = 0,01 × 25 - 2,5 = 0,25 - 2,5 = - 2,25

2. y(250) = 0,01 × 250 - 2,5 = 2,5 - 2,5 = 0

3. y(2,5) = 0,01 × 2,5 - 2,5 = 0,025 - 2,5 = - 2,475

Answer 2

Ответ:

y=0,01*25-2,5=-2,25

y=0,01*250-2,5=0

y=0,01*2,5-2,5=-2,475

Answer 3

To find the corresponding y-values for the given x-values, you can simply substitute the x-values into the equation $y = 0.01x - 2.5$.

1. When $x = 25$: $y = 0.01 \times 25 - 2.5$ $y = 0.25 - 2.5$ $y = -2.25$

2. When $x = 250$: $y = 0.01 \times 250 - 2.5$ $y = 2.5 - 2.5$ $y = 0$

3. When $x = 2.5$: $y = 0.01 \times 2.5 - 2.5$ $y = 0.025 - 2.5$ $y = -2.475$

So, for $x = 25$, $y = -2.25$; for $x = 250$, $y = 0$; and for $x = 2.5$, $y = -2.475$.
