Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used. The vector matrix [6, -2]is rotated at different angles. Match the angles of rotation with the vector matrices they produce.

the answer is d

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
