Question

15x-9y-y+1,5x при x=-6,2 y=-6,02

Answer 1

15х-9у-у+1,5х=16,5х-10у
х=-6,2 у=-6,02
16,5×(-6,2)-10×(-6,02)=-102,3+60,2= - 42,1

Answer 2

15x-9y-y+1.5x=16.5x-10y

16.5*(-6.2)-10*(-6.02)=-102.3-(-60.2)=-102.3+60.2=-42.1

Answer 3

To evaluate the expression 15x - 9y - y + 1.5x when x = -6.2 and y = -6.02, we simply substitute these values into the expression and perform the arithmetic operations:

Given expression: 15x - 9y - y + 1.5x

Substitute x = -6.2 and y = -6.02:

15(-6.2) - 9(-6.02) - (-6.02) + 1.5(-6.2)

Now, perform the arithmetic operations step by step:

1. 15(-6.2) = -93
2. 9(-6.02) = -54.18
3. -(-6.02) = 6.02
4. 1.5(-6.2) = -9.3

Putting it all together:

-93 - (-54.18) + 6.02 - 9.3

Now, simplify the expression:

-93 + 54.18 + 6.02 - 9.3

Finally, calculate the result:

= -41.1

So, when x = -6.2 and y = -6.02, the value of the expression 15x - 9y - y + 1.5x is -41.1.
