Answer:
The inequality that represent the problem is 
The solution in the attached figure
Step-by-step explanation:
Let
x ----> the number of laptops sold
y ----> the number of smartphones sold
we know that
The inequality that represent the problem is equal to

The solution of the inequality is the shaded area
Remember that the number of laptops or the number of smartphones must be a whole positive number
The graph in the attached figure
The equation of a line is written in form y = Mx+ b
M is the slope, also known as the gradient.
You are given the gradient and one point , which is an x and y value. Using that solve for b:
1. Gradient = 2, x = 4, y= 3
3 = 2(4) + b
3 = 8 + b
Subtract 8 from both sides:
B = -5
The equation becomes y = 2x-5
2. Gradient = -3, x= -1, y = 7
7 = -3(-1) + b
7 = 3 + b
Subtract 3 from both sides:
B = 4
Equation becomes: y = -3 +4
In the picture, we could see that the grid's dimension is 6 by 6. Therefore, there were 6 times 6 equal 36 squares where the coin can be dropped. Solving for the probability that coin will fall in the shaded region, we have:
Probability = 8/36
Probability = 2 / 9
The answer is the letter "a" which is 2/9.
Hyp^2 = 8^2 + 9^2
hyp^2 = 64 + 81
hyp^2 = 145
