<u>ANSWER: </u>
The algebraic expression for one-eight of the sum of a number and three is 
<u>SOLUTION:
</u>
Given, "x" represent the unknown value.
We have to write the algebraic expression for:Here, the number is unknown term, so x represents the number.
Now according to given information ,
One - eight of the sum of a number and three.
→
of the sum of x and 3
→ 
→ 
→ 
Hence the algebraic expression for one-eight of the sum of a number and three is 
<h2>
Answer:</h2><h3>b. n is odd</h3><h2>
Step-by-step explanation:</h2>
In this problem, we assume that
is a whole number. The definition of inverse functions tells us that a function
has an inverse function if and only if the function is one-to-one, that is, if there is no any horizontal line intersecting the graph of
at more than one point. This only happens if
is odd. This is called the Horizontal Line Test for Inverse Functions. So let's take two examples:
FIRST:

Since n is even, an horizontal line will pass through two points as indicated in the first figure below.
SECOND:

Since n is odd, an horizontal line will pass through just one point as indicated in the second figure below.
Answer:
this question doesnt make a lot of sence but i think its 90
Step-by-step explanation:
45+45 = 90
since ats a triangle 180-90 = 90
also the right angle with the red aquare is 90 degrese so i its 90
