Question

(-0,4x-0,2y)*6+4(1,1 x-2,2y) упростите выражение и найдите его значение,если x=0,5 y= -0,1

Answer 1

- 2,4Х - 1,2У + 4,4Х - 8,8У = 2Х - 10У
2 х 0,5 + 10 х 0,1 = 1 + 1 = 2

Answer 2

(-0,4х-0,2у)•6+4(1,1х-2,2у)=-2,4х-1,2у+
4,4х-8,8у=2х-10у=2•0,5-10(-0,1)=1-(-1)
=1+1=2

Answer 3

To simplify the expression and find its value when x = 0.5 and y = -0.1, let's substitute the given values into the expression:

Given expression: (-0.4x - 0.2y) * 6 + 4(1.1x - 2.2y)

Substitute x = 0.5 and y = -0.1 into the expression:

(-0.4 * 0.5 - 0.2 * -0.1) * 6 + 4(1.1 * 0.5 - 2.2 * -0.1)

Now, perform the calculations:

(-0.2 + 0.02) * 6 + 4(0.55 + 0.22)

Simplify further:

(-0.18) * 6 + 4(0.77)

Now calculate:

-1.08 + 3.08

Finally, we get:

2

So, the value of the expression when x = 0.5 and y = -0.1 is 2.
