15. Which statement explains why 30 is considered an irrational number?
1 answer:
Consider the given number is in question as well as in options.
Given:
is considered as an irrational number.
To find:
The reason for given statement.
Solution:
We have,
When evaluated, results in a nonterminating (infinite digits after decimal) and nonrepeating decimal, which is considered an irrational number.
Therefore, the correct option is C.

Answer:
The figure is attached down
Step-by-step explanation:
To graph a line you must have its equation
The form of the linear equation is y = m x + b, where
- m is its slope
- b is the y-intercept (y at x = 0)
∵ The slope of the line is
∴ y = x + b
- To find b substitute x and y in the equation by the coordinates
of a point on the line
∵ The line passing through point (-5 , -4)
∴ x = -5 and y = -4
∵ -4 = (-5) + b
∴ -4 = + b
- Subtract from both sides
∴ = b
∴ y = x -
To draw the line substitute x by any two values and find their ys
∵ x = -2
∴ y = (-2) -
∴ y = -6
∴ The line passing through point (-2 , -6)
∵ x = 1
∴ y = (1) -
∴ y = -8
∴ The line passing through point (1 , -8)
∵ x = 4
∴ y = (4) -
∴ y = -10
∴ The line passing through point (4 , -10)
Now we can make a table to draw the line
→ x : -5 : -2 : 1 : 4
→ y : -4 : -6 : -8 : -10
