1. Image of A is, A' (-7,-2)

2. Pre image of B' is, B (6,6)

3. Image of C is, C' (-3,-5)

4. The side which is congruent to side AB is, A'B'

5. The angle that is congruent to angle C is C'

6. The translation is 9 units left and 6 units down, so (x,y) becomes (x',y') where x' = (x-9) and y' = (y-6)

7.

a. The translation is 2 units right and 8 units down,

so, P (x,y) to P' (x+2,y-8)

b. Quadrilateral PQRS becomes P'Q'R'S' where the translation is 2 units right and 8 units down. Both quadrilateral are same in shape, length and size, their co-ordinates are different, their co-ordinates translated as follows,

P (-4,5) to P' (-2,-3)

Q (0,5) to Q' (2,-3)

R (2,1) to R' (4,-7)

S (-4,1) to S' (-6,-7)

Solve the linear system using substitution. Show your work.
y = -3x + 3
4x +3y = -1

Answers

Sub y in the second equation by y in the first equation:
We get 4x+3(-3x+3)=-1
4x-9x+9=-1
-5x=-10
x=2
Sub in the first equation
y=-3(2)+3
y=-3

Answer:

x=2 and y=-3

Step-by-step explanation:

y=-3x+3, 4x+3y=-1 solve using substitution

y=-3x+3 solve y=-3x+3 for y

4x+3y=-1

4x+3(-3x+3)=-1 simplify both sides of the equation

-5x+9=-1

-5x+9-9=-1+-9 add -9 to both sides

-5x=-10

-5x/5=-10/-5 divide both sides by -5

x=2

substitute 2 for x in y=-3x+3

y=(-3)(2)+3

y=-3 simplify both sides of the equation

answer; x=2 and y=-3

When they say find the difference, it’s a subtraction equation.
