Answer:
Answer is B
Step-by-step explanation:
If point D with coordinates (a,b) is reflected over the line y=x then the image point D' coordinates are (b,a) (see picture for details).
The middlepoint M of segment DD' lhas coordinates and lies on the line y=x (since its coordinates are equal), DD' is perpendicular to the line y=x and DM=D'M. All these remarks show that the point D' is the image point of D.
Answer:
c=144
Step-by-step explanation:
The given equation is 
If this equation has 12 and -12 as roots, then the roots must satisfy the equation.
We substitute x=12 to obtain
Solve for c to get:
This implies that:
We could have also substitute x=-12 to get the same result.
