Answer:
(9, 27 )
Step-by-step explanation:
Since the dilatation is centred at the origin, multiply each of the coordinates of the original point by the scale factor of 3
(3, 9 ) → (3(3), 3(9)) → (9, 27 )
Answer:
use the formula given in the pic and you will get the answer
X = 3 (Explanation: First, calculate the product. Move the constant to the left-hand side and change its sign. Then, write -3x as a sum. Factor out x from the expression. Next, use a²- b² = (a-b)(a+b) to factor the expression. Factor out from the expression. Then, distribute through the parentheses. When the product of factors equals 0, at least one factor is 0. After that, solve the equation for x. Finally, find the union.
