Step-by-step explanation:
Hi there!
The answer is at the attachment.
Have a nice day.
Answer:
No.
Step-by-step explanation:
An irrational number has never-ending decimals.
A rational number can be written as a fraction or has a terminating decimal.
-7.8 can be rewritten into a fraction. Its decimal also terminates. Therefore, it is not irrational but rational.
We have to solve the system of equations by Cramer's rule.
The coefficient matrix is given by

Let us find the determinant of coefficient matrix.

For X-matrix

Now, we find its determinant

For Y-matrix

Now, we find its determinant

Therefore, the value for x is given by

The value for x is 5.
X = x1+rx2/1+r ; y = y1+ry2/1+r donde r es la razón
aplicando la formula anterior las coordenadas serian x= -4/7 ; y=-11/7
donde x1 es la primera componente de punto A x2 la segunda componente del punto A y así mismo con Y<span />
Answer:

Step-by-step explanation:
we have

In this problem
The graph is shifted down by 9 units
That means----> The translation is 6 units down
the rule of the translation is
(x.y)-----> (x,y-9)
therefore
The equation of the new graph is equal to
