On a coordinate plane, 2 quadrilaterals are shown. The first figure has points A (negative 2, 1), B (negative 4, 1), C (negative

4, 5), and D (negative 2, 4). Figure 2 has points A prime (2, 1), B prime (4, 1), C prime (4, 5), and D prime (2, 4). What is the rule for the reflection? rx-axis(x, y) → (–x, y) ry-axis(x, y) → (–x, y) rx-axis(x, y) → (x, –y) ry-axis(x, y) → (x, –y

The rule of reflection is ry-axis (x , y) → (-x , y) ⇒ 2nd answer

Step-by-step explanation:

Let us revise some transformation

  • If point (x , y) reflected across the x-axis , then its image is (x , -y) , the rule of reflection is rx-axis (x , y) → (x , -y)
  • If point (x , y) reflected across the y-axis , then its image is (-x , y) , the rule of reflection is ry-axis (x , y) → (-x , y)

∵ The first quadrilateral has vertices

   A (-2 , 1) , B (-4 , 1) , C (-4 , 5) , D (-2 , 4)

∵ The second quadrilateral has vertices

    A' (2 , 1) , B' (4 , 1) , C' (4 , 5) , D' (2 , 4)

- The x-coordinates of point A' , B' , C' , D' have the same values

   and opposite signs of the x-coordinates of points A , B , C , D

∴ A' , B' , C' , D' are the images of A , B , C , D after reflection

   across the y-axis

∴ The rule of reflection is ry-axis (x , y) → (-x , y)

The rule of reflection is ry-axis (x , y) → (-x , y)

Find the dimensions of a rectangle whose width is 7 miles less than its length and whose areas is 78 square miles.
tatuchka [14]
W = L - 7
WL = 78

(L-7)L = 78

L^2 - 7L - 78 = 0
Factorize: (L-13)(L+6) = 0

L = 13 or -6

A length cannot be negative, so the length must be 13 miles.
The width is 13-7 = 6 miles.

7 + 2y = 8x 3x - 2y = 0 Solve the system of equations by substitution. (70/3, 140/9) (7/5, 21/10) no solution coincident
Wittaler [7]
So we have the system of equations:
7+2y=8x equation (1)
3x-2y=0 equation (2)

To use substitution, we are going to solve for one variable in one of our equations, and then we are going to replace that value in the other equation:
Solving for x in equation (2):
3x-2y=0
3x=2y
x= \frac{2}{3}y equation (3)

Replacing equation (3) in equation (1):
7+2y=8x
7+2y=8( \frac{2}{3} y)
7+2y= \frac{16}{3} y
7= \frac{10}{3} y
y= \frac{7}{ \frac{10}{3} }
y= \frac{21}{10} equation (4)

Replacing equation (4) in equation (3):
x= \frac{2}{3}y
x=( \frac{2}{3} )( \frac{21}{10} )
x= \frac{7}{5}

We can conclude that the solution of our system of equations is <span>(7/5, 21/10)</span>
