Answer:
Step-by-step explanation: We are given to graph the following equation on a piece of paper:
Then, we are to select the correct choice of the graph that matches with the graph we have drawn.
Writing the inequality (i) as an equation, we get
Since it is a linear equation in two variables, so we need only two points to draw the graph.
At x = 0, we have
at x = -4, we have
So, (0, 2) and (-4, -1) are two points on the line.
We draw the line as shown in the attached figure below. Also, the line is dotted because the points on the line are not included.
Since so the region below the straight line will be shaded.
We see that the drawn graph below matches with the graph (A).
Thus, the correct option is (A).

Step-by-step explanation:
Given parameters
Percentage of all teachers the works in summer = 85%
Number of teachers sampled = 6 teachers
Unknown:
The probability that they all work in summer = ?
Solution:
Now, to solve this problem, let us find the number of teachers that works in summer from the given size;
Number of teachers = 85% x 6 = 5.1;
Since it is not possible to have 5.1 people, the number of teachers will be 5
The probability =
Answer:
x = 4/3; y = 11/3
Step-by-step explanation:
y = -x + 5 and 5x + 2y = 14
Since the first equation is already solved for y, we can use the substitution method.
Substitute y of the second equation with -x + 5.
5x + 2y = 14
5x + 2(-x + 5) = 14
5x - 2x + 10 = 14
3x + 10 = 14
3x = 4
x = 4/3
Now we substitute x of the first equation with 4/3 and solve for y.
y = -x + 5
y = -4/3 + 5
y = -4/3 + 15/3
y = 11/3
Solution: x = 4/3; y = 11/3
