The image of a point is given by the rule ry = –x(x, y) → (–4, 9). what are the coordinates of its pre-image?

The coordinates of its pre-image = A (-9.4)

Transformation is a change in shape or change in location from a building to another build.

A build can be changed in shape or location using transformation

There are several forms of transformation, including translation, dilation, rotation or reflection.

Reflection from a point or shape is a reflection of a point or shape to a certain line called the mirror axis

A point A (x, y) is reflected on the line y = -x so that the shadow of point

A '(x', y ') is obtained. The relationship between these two points is determined by:

x '= -y

y '= -x

A (x, y) --- (y = -x )---> A '(- y, -x)

y = –x (x, y) --> (–4, 9).

A shadow of point A '(- 4.9) which is reflected by the line y = -x, the starting point of the relation formula above is:

x '= -y

-4 = -y

4 = y

and

y '= -x

9 = -x

-9 = x

So the starting point = A (-9.4)

hi! i think the answer is 1/2 : )

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
