1. Using a ruler and a pair of compasses only. construct
i.
Triangle PQR with |PQ l=5.5cm IPR| = 6.5cm and <Q PR=120
point S on QR such that it is equal distance from
|PQl and IPR|

2. Measure IPS|

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .

What is the value of x in the following equation? -3x-2=2x+8

Witch represents the inverse of the function f(x)=1/4x-12
