Answer:

Step-by-step explanation:
If two variables are the same when they are multiplied it becomes that variable squared.
8 x C x C
4x + 7y = 60
-4x + 7y = -4
------------------add
14y = 56
y = 56/14
y = 4
4x + 7y = 60
4x + 7(4) = 60
4x + 28 = 60
4x = 60 - 28
4x = 32
x = 32/4
x = 8
so ur solution is : (8,4)
The vertex of the absolute value function f(x) = |x| is (0,0).
What about <span>f(x)=-|x+2|-2? This can be re-written as f(x) = -|x-(-2)| -2.
Three things happen here: first, the graph of f(x) = |x| must be inverted, so that it opens down instead of up; second, the resulting graph must be translated 2 units to the left; and third, the resulting graph must be translated 2 units down.
