Let f(x)=ax+b
11a+b=23.55
12a+b=25.35
solve: a=1.8 b=3.75
so ..
f(x)=1.8x+3.75
if x=31 , f(x)=59.55

Answer:
The midpoint of the segment is (6,5)
Step-by-step explanation:
To find the midpoint of a segment we use the formula
midpoint = (x1+x2)/2, (y1+y2)/2
= (10+2)/2 , (7+3)/2
= 12/2, 10/2
=6,5
The midpoint of the segment is (6,5)
Answer:
The probability that they sit next to each other is 50%.
Step-by-step explanation:
Consider the provided information.
It is given that there are four seats within the row are first come, first served during boarding.
There are 4 seats and 2 customers (Karen and Georgia)
The total number of ways in which Karen and Georgia can sit is: 
Now if they will sit together, then consider Karen and Georgia as a single unit.
Thus, the number of ways in which they can sit together is: 
The required probability is:

Hence, the probability that they sit next to each other is 50%.
The value of x=20
Step-by-step explanation:
We need to find the value of x
We are given a right angle which is equal to 90°
So, all three angles must sum to 90°
Our equation will be:

Solving and finding value of x

So, the value of x=20
