Answer:
B. move forward 7, left 6, and down 5
Step-by-step explanation:
By the convention of 3D geometry, the coordinates of a point (x,y,z) represent how far the point is from the origin forward-backward , right/left , up-down respectively with prior one for the positive coordinate and latter for the negative coordinate.
so we need to move forward 7 for x=7 then to left 6 for y=-6 and then down 5 for z=-5.
perimeter = 2width + 2 length
102 = 2(x+9) + 2x
102 = 2x + 18 +2x
102 = 4x +18
84 = 4x
21 = x
Length = x = 21 inches
Width = x + 9 = 21 + 9 = 30 inches
B) The line will shift down 2 units.
C) The line will shift right 2 units.
D) The line will shift left 2 units.
The graphchanges from line will shift up 2 units.
A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.
Given:
y = 2x - 4.
and, if the equation is changes to y= 2x- 2.
as, function goes from y = 2x - 4 + 2
y= y = 2x - 2
The addition of 2 shows there is shifting upside.
Thus, The line will shift up 2 units.
