Answer:
Part A:
The sequence of transformation that maps triangle DEF to triangle GHI are;
1) A reflection across the y-axis (x, y) →(-x, y) and
2) A translation 6 units down, (-x, y - 6)
Part B:
1) Yes
2) The points of the triangle GHI obtained from the mapping of triangle DEF using the given transformation are corresponding therefore, the mapping proves that the two triangles are congruent
Step-by-step explanation:
Part A:
The given coordinates of the vertices of triangle DEF are;
F(-1, 5), D(-5, 2), and E(-3, 1)
The given coordinates of the vertices of triangle IHG are;
I(1, -1), H(3, -5), and G(5, -4)
Therefore, the transformation that maps ΔDEF to ΔGHI are
1) A reflection across the y-axis (x, y) →(-x, y) and
2) A translation 6 units down, (-x, y - 6)
Reflection of point F(-1, 5) across the y-axis gives → (1, 5)
Followed by a translation 6 units down gives;
(1, 5) →T(y - 6) → I(1, -1)
Reflection of point D(-5, 2) across the y-axis gives → (5, 2)
Followed by a translation 6 units down gives;
(5, 2) →T(y - 6) → G(5, -4)
Reflection of point E(-3, 1) across the y-axis gives → (3, 1)
Followed by a translation 6 units down gives;
(3, 1) →T(y - 6) → H(3, -5)
Part B:
1) Yes mapping triangle DEF onto triangle GHI proves that the two triangles are congruent
2) The points of the triangle GHI obtained from the mapping of triangle DEF are the same, therefore, the mapping proves that the two triangles are congruent

Write an equation, please help
Answer:
y = -6/5x + 2
Answer:
5\6x-2
Step-by-step explanation:
Y=(10-6x)\5
Y= 2-6\5x
Slope of line 1 = -6\5
Slope of line 2*(slope of line 1 )= -1
Slope of line 2 *-6\5=-1
Slopes of line 2 = 5\6
(X-x0)m = y-y0
(X-6)*5\6=y-3
5\6x -5 = y-3
Y= 5\6x -2

Anna has more money than Betty. If Anna gave Betty $200, then they would have the same amount of money. While if Betty gave Anna $220, Anna would then have twice as much as Betty. Calculate the amount of money each girl has using the substitution method
Answer:
Anna has $1460
Betty has $1060
Step-by-step explanation:
let Anna's money be x
and Betty's money be y
If Anna gave Betty $200, then they would have the same amount of money
Anna's money will reduce by 200
x=x-200
Betty's money will increase by 200
y= y+200
if they have the same amount of money, the difference will be zero
x-200=y+200
x-200-y-200=0
x-y-400=0
x-y=400--------------1
this means that Anna has $400 more than Betty
if Betty gave Anna $220, Anna would then have twice as much as Betty.
Betty's money will reduce by 220
y=y-220
Anna's money will increase by 220
x=x+220
Anna's money will double that of Betty's
x+220=2(y-220)
x+220= 2y-440
x=2y-440-220
x=2y-660--------------------2
put x= 2y-660 in eqn 1
(2y-660)-y=400-------------------------1
2y-y=400+660
y= 1060
so Betty has $1060
put y= 1060 in eqn 1
x-y=400
x-1060=400
x=400+1060
x=1460
so Anna has $1460
