Answer:
Step-by-step explanation:
Whenever you add two number x and -x and it becomes 0 . IT is the identity property.
Ex:
-1/3 + 1/3 = 0
-1 + 1 = 0
-58 + 58 = 0
I think the value of x is 15
<span>All real numbers that are greater than –6 but less than 6 is written as -6 < x < 6</span>
Y=-6-x is not equal to 2x+y=12. Both sides were not divided by two when it was simplified.
f(x) is a quadratic equation with the x-side squared and a is positive which means that the graph of the function is a parabola facing up. The range of f(x) is given by {y|y ≥ k}, where k is the y-coordinate of the vertex.
, written in vertex form is
, where (h, k) = (-1, -11)
Therefore, range ={y|y ≥ -11}
