There are infinitely many rules. SOme of these are:
y = x/80
y = 80/x
y = x + 79
y = 81 - x
y = sqrt(x+1) - 8

What is the rule if x is 9 and y is negative 3?
There is no specific rule. y = -sqrt(x) y = x - 12 y = -x/3 y = x2 - 84 are all possible.
What two numbers multiply to give 80 and add together to give -48?
32
What is the graph created by the rule y equals x plus 1?
The graph of y = x + 1 is a straight line with slope 1 which passes through the point (0, 1) If you have y < x + 1, then it is the area under the line y = x + 1 and is shown by shading the area under the line. If you have y > x + 1, then it is the area above the line y = x + 1 and is shown by shading the area above the line.
What is the rule y is a third as much as x?
y = x/3
What two numbers when multiplied give you -80 and when added give you -1?
-81
Two numbers have a product of 80 their sum is 21?
Let the two numbers be x and y. According to question, x * y = 80.....................(1) and x + y = 21.................................................(2) (1) implies that y=80/x......................................(3) Now, Substituting this value in equation (2) we get, x + 80/x=21 or x2 - 21x + 80=0. Solving this quadratic equation x=16 and x=5. If x=16, then (3) implies y=5 If x=5, then (3) implies y=16. Hence the two numbers are 16 and 5.

What is the rule if x is 1 and y is 5 in a function table?
There is no specific rule. Among the infinitely many possibilities are y = 5 (whatever x is) y = x + 4 y = 27x - 22 y = x2 + 4x y = 28x/4 - 2
What is the function rule if x is 1 2 3 4 5 and y is 2 6 12 20 30?
y = x(x + 1)
What is the rule for a reflection across the y-axis followed by a translation 1 unit to the right and 4 units up?
(x' , y') = (-x + 1 , y + 4)
How do you solve by Cramer's rule 2x-y 5 x-2y 1?
If you mean: 2x-y=5 and x-2y=1 then by multiplication, elimination and substitution it works out that x=3 and y=1
What is the function rule of 5 less than one fourth of x is y?
That's the function rule.
What is the rule if x is 9 and y is negative 3?
There is no specific rule. y = -sqrt(x) y = x - 12 y = -x/3 y = x2 - 84 are all possible.
What is the ordered pair rule?
The rule for a set of ordered pairs is the statement that states the relationship of of a certain value to another value.For example:given the set of ordered pair { (1,2) , (3,4) , (5,6) , (7,8) }we notice that the value of y is increased by 1 as the value of x varies.For instance, in the first ordered pair which is (1,2) where 1 is x and 2 is y such that (x,y), 1 increased by 1. In other words, x is increased by 1.So we say that the rule of the ordered pair is:{(x,y) | y = x + 1 }read as "The set of ordered pairs such that y is equal to x plus one"
