There are 7 numbers. 7 X 45 equals 315. 40+45+48+54+45=232.
315-232=83.
The 2 numbers can each have different values, such as 41 and 42, or 40 and 43. The numbers must add up to 83, though.

Considering the given table and the periodicity concept, it is found that the data set is not periodic.
<h3>What is the period of a data-set?</h3>
The period of a function is given by the <u>distance between it's repetitions</u>.
An example of a periodic data-set with a period of 3 would be 1,2,3,1,2,3,1,2,3,...
In this problem, looking at the table, it is found that there are no patterns of repetitions, that is, the number of cars washed do not follow a repeated pattern, hence the data set is not periodic.

Answer:
YES, they are equal
Step-by-step explanation:
Given the expressions
h(x) = 2x – 3;j(x) = - 4x + 6; k(x) = – 2x + 3
h(x) + j(x) = 2x – 3 + (-4x + 6)
h(x) + j(x) = 2x - 3 -4x + 6
h(x) + j(x) = 2x - 4x -3 + 6
h(x) + j(x) = -2x + 3 = k(x)
This shows that h(x) + j(x) = k(x)
