For the answer to the question above, a system of equations has no solution when the lines representing the equation are parallel but do not coincide. For two lines to be parallel, the must have the same gradient i.e. coefficient of x when y is made the subject of formula must be equal.
If one of the equations is
y = 8x + 7,
then the other equation will be
y = 8x - 7
Answer:
x=17/2 y=1/6
Step-by-step explanation:
-1(x+3y=9)
1(x-3y=8)
_________
-x-3y=-9
x-3y=8
________
-6y/6=-1/6 y=1/6
x+3(1/6)=9
x+ 1/2=9
- 1/2 - 1/2
x=17/2

Answer:
A correlation coefficient is a numerical measure of some type of correlation, meaning a statistical relationship between two variables. The variables may be two columns of a given data set of observations, often called a sample, or two components of a multivariate random variable with a known distribution.
