HELP NEED AS FAST AS COULD Which transformations were used to create congruent trapezoid WXYZ from trapezoid WXYZ?

rotation of 180° about the origin and a reflection across the y-axis

rotation of 90° clockwise about the origin and a reflection across the x-axis

translation and reflection across the y-axis

translation and rotation of 180° about the origin

D: It is 'translation and rotation of 180 degrees about the origin.

Step-by-step explanation:

You have to rotate it 180 degrees to turn it 'upside down'. Then from there, you translate the shape about its origin. Which is similar to reflecting from the origin.

40 x 50 = 2000

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
