3(2n-9) is the equation that is equivalent to 6n-27.
extraneous root is a solution o an equation that seems to be right but when we check it (by substituting it into the original equation) it turns out not to be right
Answer:
1250 g
Step-by-step explanation:
12.5% of 10 kg
12.5% of 10000 g
.125 of 10000 g
.125 * 10000 g
1250 g
Since the dilatation is centred at the origin then multiply each of the coordinates of the vertices by the scale factor.
(- 4, 2 ) → (- 4, 2 ) → (- 2, 1 )
Similarly
(- 2, 8 ) → (- 1, 4 )
(2, 4 ) → (1, 2 )
Answer: the equation is 2n-10
