20 % of 2 is equal to  a. 20  b. 4  c. 0.4  d. 0.04

The answer is C. 0.4.

The first step to this problem is to find out what is 1% of 2. You can do this by dividing 2 by 100. Which would give you 0.02.

The next step is to multiply 1% of 2 by 20% to find out what 20% of 2 is. The answer you would get would be 0.4.

Equation:

1% of 2  -  2 ÷ 100 = 0.02

20% of 2  -  0.02 x 20 = 0.4

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
