The only answer that makes sense is the second one. 

"A translation 10 units down, and a translation 8 units the right."

Answer:

Option B is correct.

Step-by-step explanation:

Given Coordinates of the vertices of the Quadrilateral,

A( -5 , 4 ) , B( -6 , 6 ) , C( -2 , 6 ) and D( -4 , 4 )

Coordinate of the vertices after transformation,

A'( 2 , -6 ) , B( 2 , -4 ) , C( 6 , -4 ) and D( 4 , -6 )

We need to find the transformation.

Reflection and rotation is not done in this transformation as while doing reflection and rotation position of edge change.

So, It is translated 10 unit down then 8 unit right is the correct answer.

Therefore, Option B is correct.

7x + 2y = 7<br> -14x + 2y = -11<br> Solve by substitution
kvasek [131]

Answer:

x = 6/7, y = 1/2

Step-by-step explanation:

7x + 2y = 7

-14x + 2y = -11

1) 7x + 2y = 7

2y = 7 - 7x

2) -14x + 2y = -11

-14x + 7 - 7x = -11

- 21x = -11-7

- 21x = - 18

x = 18/21 = 6/7

3) 2y = 7 - 7x = 7 - 7*(6/7) = 7 - 6 = 1

2y = 1

y = 1/2

Solve the value of y for the given values of x: 4x = 3y - 7; x= 4,5,6
julia-pushkina [17]
Thhe easiest way would be to solve for y first
4x=3y-7
add 7
4x+7=3y
divide both sides by 3
(4x+7)/3=y

try each
x=4
(4(4)+7)/3=y
(16+7)/3=y
(23)/3=y
7 and 2/3=y
(4,7.66666)


x=5
(4(5)+7)/3=y
(20+7)/3=y
(27)/3=y
9=y
(5,9)

x=6
(4(6)+7)/3=y
(24+7)/3=y
(31)/3=y
10 and 1/3=y
(6,10.333)



(4,7.66666)
(5,9)
(6,10.333)

when x=4, y=7 and 2/3
when x=5, y=9
when x=6, y=10 and 1/3
