There are different levels of classification when it comes to numbers. The general classification is between real numbers and imaginary numbers. Imaginary numbers are those with 'i' in them which is equal to √-1. Next, real numbers can be classified as rational or irrational. Irrational numbers are those that can't be expressed into fractions. Lastly, rational numbers are classified into integers and fractions.
The line which rises to the left has slope of -1/3 and y intercept of 2 so we have
y = -1/3x + 2
3y = -x + 6
x + 3y = 6
Shading is below and the line is solid so the inequality is
x + 3y ≤ 6
The other line has equation
y = 3x - 1
and inequality is
y ≥ 3x - 1
The answer is B

The number of squares tiles that will be required to floor the rectangular store is approximately 1284 tiles
<h3>How to find the number of tiles used for the rectangular floor?</h3>
The rectangular store measures 6.5m by 7.9m.
Therefore,
area of a rectangle = lw
where
Therefore,
area of a rectangle = 6.5 × 7.9
area of a rectangle = 51.35 m²
The square tiles used for the floor is 20cm each. Therefore,
20 cm = 0.2m
hence
area of the square tile = 0.2² = 0.04 m²
number of tiles = 51.35 / 0.04 = 1283.5
number of tiles ≈ 1284 tiles
