Answer:
(x, y) ⇒ (-x, -y)
Step-by-step explanation:
There are a couple of ways you can go at this.
1) Rotation by 180° in either direction is the same as reflection across the origin. That reflection is identical to reflection across both the x- and y-axes, in either order, so negates both coordinates. The transformation rule is ...
(x, y) ⇒ (-x, -y)
__
2) The rule for a general rotation by angle α is ...
(x, y) ⇒ (x·cos(α) -y·sin(α), x·sin(α) +y·cos(α))
For α = 180°, sin(α) = 0 and cos(α) = -1. This makes the rule for rotation by 180° be ...
(x, y) ⇒ (-x, -y)
Answer:
(3t + 7) (t + 1)
Step-by-step explanation:
3t^2 + 10t + 7
(3t^2 + 3t) (7t+7)
3t (t+1) 7 (t+1)
(3t+7) (t+1)
Answer:
40x² + 65x + 25
Explanation:
We will just multiply each term from the first bracket by each term from the second and then combine like terms to get the final expression.
This would be done as follows:
(5x + 5)(8x + 5)
5x(8x) + 5x(5) + 5(8x) + 5(5)
40x² + 25x + 40x + 25
40x² + 65x + 25
Hope this helps :)
