Question

x =10.0 +0.1 and y =10.0+ 0.1 than 2x - 2y is equal to
(1) 0.0+0.1
( 2)(0.0+0.4)
(3) (20 +0.2
(4) Zero ​

Answer 1

Answer:

Given data states the value of x and y and is asking the value of 2x – 2y,

Therefore putting the value of x and y into the equations,

Substituting x = 10.0 + -0.1 and y = 10.0 + -0.1 in 2x-2y = {2[10.0 +(-0.1)] – 2[10.0 + -(0.1)]}

Rearranging them, we get = {2[10.0-10.0] +2[(-0.1)+(-0.1)]} = {2 [0.0] + 2[-0.1-0.1]} ={0.0 + 2 x [-0.2]} =0.0- 0.4

Hence 2x -2y = -0.4 .

Answer 2

Answer:

zero

Explanation:

(20+0.2) - (20+0.2)

20 + 0.2 -20 -0.2

hence answer is zero
