7. Marco was asked to rotate the coordinate P(3,-4) 180 degrees about the

origin. Then, he decided to perform a

translation of (x, y+2) followed by a

dilation of 2. Marco was convinced that

P and P'" had the same coordinates. Is

Marco correct? Explain your reasoning.

the answer is the third / last answer

step-by-step explanation:

idk

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
