Proportional Relationships
A proportional relationship is one in which two quantities vary directly with each other. We say the variable y varies directly as x if:
y=kx
for some constant k , called the constant of proportionality .
(Some textbooks describe a proportional relationship by saying that " y varies proportionally with x " or that " y is directly proportional to x .")
This means that as x increases, y increases and as x decreases, y decreases-and that the ratio between them always stays the same.
The graph of the proportional relationship equation is a straight line through the origin.
The given question is a quadratic equation and we can use several methods to get the solutions to this question. The solution to the equation are 3/4 and -5/6 and the greater of the two solutions is 3/4
<h3>Quadratic Equation</h3>
Quadratic equation are polynomials with a second degree as it's highest power.
An example of a quadratic equation is
The given quadratic equation is 
Let's rearrange the equation
This implies that
The equation or formula of quadratic formula is given as
We can substitute the values into the equation and solve
From the calculations above, the solution to the equation are 3/4 and -5/6 and the greater of the two solutions is 3/4

Answer:
=1/26
Step-by-step explanation:
In a 52 card deck there are 2 red 8's ( hearts and diamonds)
P(red 8) = number of red 8's / total
=2/52
=1/26
We write to expressions since there are two unknown here which is x and y. The first expression is the <span>sum of two numbers, x and y, is 12.
x + y = 12
The second expression is that the </span><span>difference of x and two times y is 6.
x -2y = 6
Therefore, the values of x and y are 10 and 2.</span>
