Answer:
Your column vector is:
Step-by-step explanation:
The first step to solve your problem is knowing what is a column vector:
A column vector is a matrix that only has one column, and multiple rows.
The problem wants the vector to range from 15 to -25.
It means that the biggest value in the vector is 15, and the smallest is -25. Since it is from 15 to -25, the first element of your column vector is 15, and the last element is -25.
With a step size of 5
At each element, you decrease 5. So you have: 15,10,..,-20,-25.
The vector is:
Answer:
Option 3.
Step-by-step explanation:
This system of inequalities contains 2 lines.
(i)
and
(ii)
The line (i) is the one that intercepts the y-axis in and the x-axis in . Therefore the line (i) is drawn with blue in the graph.
The inequality is:
We can clear the variable-y:
Then, the region that represents this inequality are all the values in which the y-axis is less than the function . That is, the entire area below the blue line.
Then, line (ii) is represented by the color orange. It cuts the y axis in and the x axis in . Therefore we can discard the first two options shown in the image because there the orange line cuts in .
The inequality for this line is:
so:
Then, the region that represents this inequality are all values in which the y-axis is smaller than the function . That is, the entire area below the orange line.
Finally the region sought is the one below the orange line and at the same time below the blue line. That is, the third option
