<u>Answer:</u>
Option D is the correct answer.
D. This is a linear function because there is a common difference of 2.
<u>Step-by-step explanation:</u>
Linear function--
A function is said to be linear if the rate of change is constant.
i.e. the function is increasing by a fixed constant.
Here the table is given by:
Hour (x) Number of Customers f(x)
1 2
2 4
3 6
From the table of values we observe that as the value of increasing by 1 the value of y is increasing by 2.
i.e. the rate of change is constant i.e. 2.
Also, the common difference is 2.
Since,
4 - 2 = 2
and
6 - 4 = 2
Hence, the table represents a linear function.
Answer:
Jude is not correct
Step-by-step explanation:
The volume of a square pyramid is given as:

where a = base edge and h = height
Hence, the volume of the square pyramid with base edge of 7 in and height of 7 in is:

V =
≅ 
The volume of a cylinder is given as:

where r = radius and h = height
Hence, the volume of a cylinder with radius of 7 in and height of 7 in is:

V =
≅ 
Since their volumes are not equal, Jude is not correct.
Oh dear~This can only be simplified。
15X+18y
3(5X+6Y)
That's your answer.
