Answer:
x= 10 and y= -1
Step-by-step explanation:
Rewrite your second equation Y= -2x+ 19 then plug it into the first equation.
x- (-2x + 19) = 11
x + 2x - 19 =11
3x - 19 = 11
3x = 30
x = 10
The plug that answer into the first equation and solve.
10 - y = 11
-y = 1
y = -1

A number is even if it ends with an even digit, so 8 must be the last one.
Now, the digits to the left are more worth than those on the right, so if you want a big number you have to stack the greatest digits to the left, otherwise if you want a small number you have to stack the smallest digits to the left.
So, the greatest number is 7538, the smaller is 3578.
Replace x with (x/3).
Note: (x/3) = (1/3x).
f(x/3) = (x/3)^3 + 5
Using a graphing calculator, we can easily see that CHOICE 4 is the right graph.
