Answer:
The answers are:
(x,y,z)=
(5,1,-2)
(1,-2,5)
(-2,5,1)
(5,-2,1)
(-2,1,5)
(1,5,-2)
Step-by-step explanation:
In order to determine the answer, we have to express the final number into a addition.
The number 700070.07 may be written by:
700000+70+0.07
Then, we can express every number into a scientific notation,that is, at the form:
700000
a=7
b=5
70
a=7
b=1
0.07
a=7
b=-2
So, in this case, we have three numbers: 5, 1, -2. The set of values are the combination of these numbers, in total 6 set of numbers.
Finally, the possible set of values for x, y, z are:
(5,1,-2)
(1,-2,5)
(-2,5,1)
(5,-2,1)
(-2,1,5)
(1,5,-2)

Answer:
Option (2). 1
Step-by-step explanation:
Coordinates of point A, B, C and D are,
A(-4, 4), B(-2, 4), C(-2, 1) and D(-4, 3).
Quadrilateral ABCD when rotated 90° clockwise about the origin,
Rule for the rotation of the vertices,
(x, y) → (y, -x)
Following the rule of rotation coordinates of the image points,
A(-4, 4) → A'(4, 4)
B(-2, 4) → B'(4, 2)
C(-2, 1) → C'(1, 2)
D(-4, 3) → D'(3, 4)
Since all image points have the positive coordinates (x and y coordinates), image quadrilateral A'B'C'D' will be located in 1st quadrant.
Option (2) is the correct option.
