Answer:
a) 3x - 6x^2y + 2xy - 2x
b) 4x^2 <u>- 3y </u>+ 2x <u>+ 7y</u>
Step-by-step explanation:
Like terms is when the terms are the same.
For example, 3x and -2x would be like terms (both have x).
Not like terms would be 4x^2 and +2x (one is just an x and the other is x^2).
I think it 5:50 but it could also be 3:50 and 2:50
Answer:
The pre-image C is (2, 5)
Step-by-step explanation:
- If the point (x, y) rotated about the origin by angle 90° clockwise, then its image is (y, -x)
- If the point (x, y) rotated about the origin by angle 180° clockwise, then its image is (-x, -y)
- If the point (x, y) rotated about the origin by angle 270° clockwise, then its image is (-y, x)
∵ Point C was rotated 270° clockwise around the origin
∵ C' = (-5, 2)
→ By using the 3rd rule above
∵ The image of the point (x, y) is (-y, x)
∴ (-y, x) = (-5, 2)
→ That means -y = -5 and x = 2
∴ x = 2
∴ -y = -5
→ Divide both sides by -1
∴ y = 5
∴ The pre-image C = (2, 5)
