Answer:

The ordered pair of W' is ( 7 , 2 ).

Step-by-step explanation:

Given: Coordinates of the vertices of Trapezoid TUVW

T( -5 , 5 )  , U( -2 , 5 ) , V( -2 , 2 )  and W( -7 , 2 )

Trapezoid TUVW reflected over the y-axis.

Reflected trapezoid name is T'U'V'W'

We need to find coordinate of W'

We know that rule for a reflection of a coordinate over the y -axis is (x,y)\rightarrow (-x,y)

Using this rule we get,

Coordinate of T' = ( -(-5) , 5 ) = ( 5 , 5 )

Coordinate of U' = ( -(-2) , 5 ) = ( 2 , 5 )

Coordinate of V' = ( -(-2) , 2 ) = ( 2 , 2 )

Coordinate of W' = ( -(-7) , 2 ) = ( 7 , 2 )

Therefore, The ordered pair of W' is ( 7 , 2 )

Simplify the given expression. (16x^2 + 15xy – 19y^2) – (3x^2 – 3xy)
ruslelena [56]

Answer:

-19 y^2 + 18 x y + 13 x^2

Step-by-step explanation:

Simplify the following:

16 x^2 + 15 x y - 19 y^2 - (3 x^2 - 3 x y)

Factor 3 x out of 3 x^2 - 3 x y:

16 x^2 + 15 x y - 19 y^2 - 3 x (x - y)

-3 x (x - y) = 3 x y - 3 x^2:

16 x^2 + 15 x y - 19 y^2 + 3 x y - 3 x^2

Grouping like terms, 16 x^2 + 15 x y - 19 y^2 - 3 x^2 + 3 x y = -19 y^2 + (15 x y + 3 x y) + (16 x^2 - 3 x^2):

-19 y^2 + (15 x y + 3 x y) + (16 x^2 - 3 x^2)

x y 15 + x y 3 = 18 x y:

-19 y^2 + 18 x y + (16 x^2 - 3 x^2)

16 x^2 - 3 x^2 = 13 x^2:

Answer:  -19 y^2 + 18 x y + 13 x^2
