Answer with Step-by-step explanation:
We are given that a function
Assign each whole number to its largest place value digit.
We have to find the value of x that makes the equation 7 a true statement.
When f(x)=7
Then, the possible values of x are 7,127,27,257,... .
Because f(7)=7
f(127)=7
f(27)=7
f(257)=7
Therefore, the value of x =7,127,257,27,..
9514 1404 393
Answer:
(x, y) = (1, -1)
Step-by-step explanation:
The augmented matrix of coefficients for these equations is ...
The row-reduction function of your calculator can find the solution to the system of equations. The result of using that function is ...
This tells you the solution is (x, y) = (1, -1).
