Is the following number rational or irrational?
2 answers:
Answer:
Rational
Step-by-step explanation:
To find out whether it is rational or irrational let's write the definitions of both
Rational: Any number that can be written as a fraction, integer, whole number, natural number
Irrational: Numbers that can't be written as a fraction
This has to be rational because every rational number can be written as a repeating decimal.
Since it can be expressed as fraction, it's a rational number.

x + (x + 3) + 
= 75
so you will add up all of the x 's but NOT the x^2
2x + 3 + = 75
Rearrange to put the x^2 in front of 2x
+ 2x + 3 = 75
subtract the 75 from both sides
+ 2x - 72 = 0

Answer:
A) y-4=-1/2(x+6)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(0-4)/(2-(-6))
m=-4/(2+6)
m=-4/8
simplify
m=-1/2
y-y1=m(x-x1)
y-4=-1/2(x-(-6))
y-4=-1/2(x+6)
