Complete the mapping of the vertices of δdef. d(2, –4) → d' e(1, –1) → e' f(5, 1) → f' what is the rule that describes a reflection across the line y = x? rx = y(x, y) →

The rule of reflection across the line y = x is

The mapping of the vertices of ΔDEF is given by :-

Step-by-step explanation:

When we reflect a point across the line y = x, the x-coordinate and y-coordinate interchanges places.

The rule of reflection across the line y = x is

Then, the mapping of the vertices of ΔDEF is given by :-

yes

step-by-step explanation:

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
