I. xy + 2y=3 Not linear equation because is grade 2 equation (xy).
II. x-2y = y Are linear equations in two unknowns (x and y).
III. 3x + 2y = 5 Are linear equations in two unknowns (x and y).

Corect ansver: C) II and III only</h2><h2>

.
Answer:
The correct answer is the third option
Step-by-step explanation:
Have different slope but have the same y-intercept, so they have no solution.
y = 1/2x - 3
To graph this, the slope 1/2 which means go up once and to the right twice and b = -3, which means the y-intercept.
second equation:
y = -1/2x -3
To graph this, the slope -1/2 which means go down once and to the right twice and b = -3, which means the y-intercept.

Given:
50% of the people that get mail-order catalogs order something.
Determine the probability that exactly 2 out of 10 people getting the catalogs will order something.
If the total number of people is 10, we can calculate the number of people who will order something from the catalogs:
10 * 0.50 = 5 people.
The probability that exactly two out of ten people will order something is:
2/5 = 0.4
Therefore, there is a 40% chance that the exact two people who received the catalogs will order something from it.
The answer would be 5,400 ( 3000 times 0.15 would be 450 then, 450 times 12 is 5,400.)
