Which table best classifies the following numbers as rational and irrational?
2 answers:
Answer:
Rational: negative 6 over 5, 3.5, 0 point 5 bar , square root of 4.
Irrational: square root of 5.
Step-by-step explanation:
We know that a rational number is a number which can be expressed in the form of ; where p belongs to integer and q belongs to the set of natural numbers.
so here the set of rational number is:
negative 6 over 5 , 3.5 as it is equal to 7 over 2 , 0 point 5 bar, and square root of 4 as it is equal to +2 or -2.
and the irrational number is:
square root of 5.

Step-by-step explanation:
To find the intercepts, that is where the graph crosses the x and y axes.
• Let x = 0, in the equation for y-intercept
• Let y = 0, in the equation for x-intercept
x = 0 : 0 + y = - 9 ⇒ y = - 9 ⇒ (0, - 9 ) ← y- intercept
y = 0 : 8x + 0 = - 9 ⇒ x = - ⇒ ( -
, 0) ← x- intercept
