Answer:
Shape a has 1 order of rotational symmetry and 1 line of symmetry
Shape b has 2 orders of rotational symmetry and 0 line of symmetry
Rotational symmetry is how many times a shape can be rotated and look the same.
Lines of symmetry are how lines can be put through the shape to make it symmetrical or the same on both sides
Step-by-step explanation:
I had to take help from my brother for the solution as I'm not very good with solid geometry. Hope you got it and thanks for sharing questions like this. It helps me to learn more.
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:
216
Step-by-step explanation:
300 x .28 = 84
300 - 84 = 216
Answer:
x = -5/2 y +4
Step-by-step explanation:
2x+5y = 8
Subtract 5y from each side
2x+5y -5y = -5y+8
2x = -5y+8
Divide each side by 2
2x/2 = -5y/2 +8/2
x = -5/2 y +4
