SOLUTION
From the sequence give
–3, 1, 5, 9, . . .
The first term, a = -3
The common difference, d = 4 (gotten by adding 4 to the next term).
The number of terms required n = 6.
Formula for sum of an arithmetic sequence is given by
Substituting these values into the equation above we have
Hence, the answer is 42, option B
Answer:
Step-by-step explanation:
A linear function has been given as,
y =
Comparing it with the slope intercept equation,
y = mx + b
b = y-intercept = 5
From the graph,
y-intercept = (-2)
From the given table,
For x = 0, f(x) = 3
Therefore, y-intercept = 3
A line passes through two points (-3, -2) and (3, 0),
Slope of the line =
=
=
Equation of a line passing through a point (x', y') and slope = m
y - y' = m(x - x')
If the point is (3, 0) and slope =
y - 0 =
y =
y-intercept of this line = (-1)
Therefore, decreasing order of the slopes will be,
Order of the functions with slopes from maximum to lease will be,
1).
2). Function represented by the table.
3). Line passing through (-3, -2) and (3, 0)
4). Function shown in the graph
