Answer:
A. Line symmetry
C. Rotational symmetry ... 45°
Step-by-step explanation:
First of all, you need to have some idea what symmetry means.
A figure has <em>line symmetry</em> if it can be folded on a line and the halves of the figure lie on top of each other.
Here, any line through opposite vertices or through the midpoints of opposite sides is a line of symmetry. This figure has line symmetry.
__
A figure has <em>rotational symmetry</em> if it can be rotated by some amount less than a full turn, and it lies on top of itself. The number of times you can do this in a full turn is the degree of the symmetry.
Here, the figure can be rotated 1/8 turn (360°/8 = 45°) and it will be indistinguishable from the original. It has rotational symmetry with angles of rotation that are multiples of 45°.

<em>Comment on symmetry of regular polygons</em>
Any regular n-gon will have rotational symmetry of degree n, and symmetry about a line through its center and any vertex or side midpoint. (For odd n, such a line through a vertex goes through the midpoint of the opposite side.)
Answer:
Step-by-step explanation:
The function t, where t(x) = 9.50x represents the amount of money Fernando earns given the number of hours, x, that he works.
The domain of a function are the set of possible values of x, the independent variable that satisfies the function.
Fernando works between 12 and 25 hours each week. It means that the statement that best represents the domain of this function for any given week would be
12 ≤ x ≤ 25
Answer:
-32x
Step-by-step explanation:
-7x+15x-40x
<em>First, you add the numbers or similar into elements from left to right to find the answer.</em>
<em>-7x+15x-40x=-32</em>
<em>-32x is the correct answer.</em>
<em>I hope this helps you, and have a wonderful day! </em>
