Answer:
Step-by-step explanation:
(x - 13)/2 = 3
x - 13 = 6
x = 19
(y - 11)/2 = -4
y - 11 = -8
y = 3

Answer:
<u>The rational numbers include all the integers, plus all fractions, terminating decimals and repeating decimals. Every rational number can be written as a fraction a/b, where a and b are integers. If a number is a whole number, for instance, it must also be an integer and a rational.</u>
<u>(idk if this was exactly what you were looking for but i hope it helps</u>
<em>No</em>. For all the things that humans are really good at, picking totally random numbers is not one of them. There are certain numbers that people are more likely to consider "random" than others; for instance, odd numbers and prime numbers tend to be popular picks as far as "random-looking" numbers go, and this trend can make so-called "random" picks a lot less random that we'd like them to be.
To get a truly random sample, using a <em>random number generator</em>, especially a <em>truly random </em>number generator, will give you a truly random sample.
If you look at the quadratic formula:
x=(-b±√(b^2-4ac))/(2a)
We can say that -b=5, b=-5
If I read it right you had ±2√7 which is equal to ±√28, and we know b=-5 so:
±√(25-4ac)=±√28
And since 3=2a, a=1.5 making the above:
±√(25-6c)=±√28
25-6c=28
-6c=3
c=-0.5
So a=1.5, b=-5, and c=-0.5 thus
y=1.5x^2-5x-0.5
We can check this by reapplying the quadratic formula to the equation above
x=(5±√(25-4(1.5)(-0.5))/3
x=(5±√(25+3))/3
x=(5±√28)/3
x=(5±√(4*7))/3
x=(5±2√7)/3
