Answer:
Step-by-step explanation:
From the picture attached,
Option A
From the given table,
Ratio of the 2nd value and 1st value =
Ratio of 3rd value and 2nd value =
There is a common ratio of 2.
Therefore, the given table will represent an exponential function.
Option B
Given recursive formula of the sequence is,
From this recursive formula sequence will be,
3, 15, 75, 375,.......
Therefore, it's an exponential function.
Option C
Given function is in the form of a linear function (y = mx + b),
Therefore, it's a linear function.
Option D
From the given table,
Difference between 2nd value to the 1st value = 8 - 4 = 4
Difference between 3rd value to the 2nd value = 12 - 8 = 4
Therefore, there is a common difference of 4 in each successive term to the previous term.
Hence, the given table represents a linear function.
Answer:
1. The slope of the line is .
2. The value of a is 18.
Step-by-step explanation:
If a line passes through two points, then the slope of the line is
(1)
It is given that the line passes through the points (-a + 3, b - 3) and (a + 3, -b). So, the slope of the line is
The slope of the line is .
(2)
If the line passing through the points (a, 1) and (6, 5), then the slope of the line is
If the line passing through the points (2, 7) and (a + 2, 1), then the slope of the line is
The slopes of two parallel lines are same.
On cross multiplication we get
Divide both sides by -2.
Therefore the value of a is 18.
