Answer:
Step-by-step explanation:
If a point (x, y) is reflected across y = -x, coordinates of the image point will be,
(x, y)→ (-y, -x)
Following this rule,
Vertices of the triangle will be,
(3, 1) → (-1, -3)
(3, -2) → (2, -3)
(6, -3) → (3, -6)
Therefore, image of the given triangle A will be,
(-1, -3), (2, -3) and (3, -6)

Answer:
The cost for painting will be $212.
Step-by-step explanation:
I am painting the walls and ceiling of a rectangular 20 x 30 ft room. The walls are 10 feet tall.
So, the total area to be painted = {2 × (20 + 30) × 10} + (20 × 30) = 1600 sq. ft.
Now, a gallon of paint covers 400 square feet and cost $53 per gallon.
So, the number of gallons of paint required will be gallons.
And the cost for painting will be $(4 × 53) = $212. (Answer)
