The triangle presented in the image has 2 axes of symmetry because it is only possible to divide it 2 times.
<h3>What are axes of symmetry?</h3>
The axes of symmetry are a concept of geometry that are classified into two groups:
- The plane axis of symmetry: This is an imaginary line that divides a figure into two parts, ensuring that the symmetrical points are at the same distance from it.
- The axis of axial symmetry: This is the symmetry around an axis, it is a point of translation and rotation in which all the semi-planes taken from a certain perpendicular bisector have identical characteristics.
According to the above, it can be inferred that the rectangle presented in the image has only two axes of symmetry.

Answer:
Let a and b integers and suppose that are even numbers. Then, exist integers k and m such that 
and 
.
Then,
Since, k and m are integers then n=k+m is an integer. Then, since a + b is of the form 2 by an integer n, then a + b is an even number.
Answer & Step-by-step explanation:
When using piecewise functions, the intervals represents what function will be used when given a certain number. So, let's begin.
For f(-3), we will use the first function because -3 is less than -1.
<em>f(-3) = 7/2 + 2(-3)</em>
<em>f(-3) = 7/2 - 6</em>
f(-3) = -5/2
For f(-1), we will use the first function again because -1 equals -1.
<em>f(-1) = 7/2 + 2(-1)</em>
<em>f(-1) = 7/2 - 2</em>
f(-1) = 3/2
For f(3), we will use the last function because 3 equals 3.
<em>f(3) = 1/4(3)</em>
f(3) = 3/4
