Question

(2х-3)у,если х=0,2;у=-0,4​

Answer 1

Ответ:

1.04

Объяснение:

(2x-3)y=2xy-3y=-0.16-(-1.2)=1.04

Answer 2

Ответ:

(2*0.2-3)*(-0.4)=(0.4-3)*(-0.4)= -2.6*(-0.4)=1.04

Answer 3

To find the value of the expression (2x - 3)y when x = 0.2 and y = -0.4, you simply need to substitute the given values into the expression and perform the calculations.

Let's plug in the values:

(2 * 0.2 - 3) * (-0.4)

Now, perform the calculations step by step:

(0.4 - 3) * (-0.4)

(-2.6) * (-0.4)

Now, multiply the two negative numbers:

2.6 * 0.4

Finally, calculate the result:

2.6 * 0.4 = 1.04

So, when x = 0.2 and y = -0.4, the value of the expression (2x - 3)y is 1.04.
