<span>Let us use the variable x for length. So width will be 1/2x + 3. Perimeter = x+x+ 1/2x + 3 +1/2x + 3 = 3x + 6 = 66 Therefore 3x = 66-6 = 60 So x = 60/3 = 20 The length is 20 cm. Therefore the width = 1/2 of 20 + 3 = 10 + 3 = 13 cm Check: 20+20+13+13 = 66</span>

State the rule that will result in the transformation below.<br> (x,y) maps to (?, ?)
Anna [14]

Answer:

(x,y) maps to (-y,x).

Use vertex I as an example.

Pre-image I is graphed at point (-3,2), while image I' is graphed at point (-2,-3) .

In order to change between these points, the x and y coordinates must be swapped, as well as multiplying the y coordinate by -1.

10 points, Solve the rational exponents, please show the work if you can :) please don't use me for points, its already happened
iogann1982 [59]
Essentially just turn the big number into an exponent so u can cancel out and be left with just the x for example 128 is the same as 2^7 and when you have it like that you simply cancel the 2 and are left with x=7

A) x=7
B) x=6
C) x=4
D) x=8
E) got cut off theres no value
F) x=2
G) x=3

Id reccomend downloading photomath for these type of questions or symbolab on your phone it shows the steps but try practicing it first :)
