Answer:
Sound requires a material medium to travel , the sound through each medium through its molecules and particles present in it .Sound travels with some speed and it's speed depends upon the nature of the medium through which it travels i.e. upon density and transparently. Speed of increases with the increase in density and decreases with the increases in temperature . Speed if sound us maximum for solid then for liquid and minimum in gases because of it's large intermolecular spaces and low density.
Any real number line ranges from negative infinity to positive infinity. A real number number line consists of all the rational and irrational numbers. Let us take three intervals which contain both the rational and irrational numbers.
First interval: [3,4]
Since every integer is a rational number, 3 and 4 are both rational. In this interval there occurs the value of π (3.14159..) which is an irrational number.
Second interval : [0,2]
0 and 2 are integers and hence are rational. In this interval, occurs √2 (1.41421...) is an irrational number.
Third interval : [2,3]
In this interval, Eulers number 'e' lie whose value is (2.718281.. )
Hence we can conclude that, there occurs an irrational number between any two rational number.

I must make some assumptions here about what you may have meant by your "<span>linear equation y=3x−5y=3x−5 y equals 3 x , minus 5."
You've written "y=3x-5" three times on the same line of type. Why is that?
Let's change what you've typed to the following:
</span><span>linear equation y=3x−5
separate linear equation y equals 3x minus 5, or y=3x-5
Please go back and ensure that you have copied down this problem precisely as it was originally presented. Be careful not to duplicate info (as you did in typing "y=3x-5," followed by "</span><span>y equals 3 x , minus 5."
</span><span>
y = 3x - 5 is, as you say, "a linear equation." The slope of this line is 3 and the y-intercept is (0, -5).
As to form: This is a "slope-intercept equation of a straight line."
Other forms include "General form of the equation of a straight line," "Point-slope form."</span>
