Answer:
(5,8)
Step-by-step explanation:
The (x,y) position is (3,2)
Translation 1 is 4 right and 4 up
Add 4 to the x position and add 4 to the y position
(3+4, 2+4)
(7,6)
Translation 2 is 2 units left and 2 units up
Subtract 2 from the x and add 2 to the y
(7-2, 6+2)
(5,8)

Answer:
(0,-5) x= 0; y= -5
Step-by-step explanation:
You can solve by using substitution. This means to solve for x on one of the equations then substituting x for the other equation and solving it.
Answer:
(x - 7)(x - 4)(x + 4).
Step-by-step explanation:
A(x) = x3 – 7x² – 16x +112
Dividing by x-7:
x^2 - 16 <-------- Quotient
-----------------------------
x-7)x^3 - 7x^2 - 16x + 112
x^3 - 7x^2
0 - 16x + 112
- 16x + 112
..............
so A(x) = (x - 7)(x^2 - 16) x^2 - 16 is the difference of 2 squares so we have:
(x - 7)(x - 4)(x + 4).
Checking by expanding the brackets:
(x - 7)(x - 4)(x + 4)
= x(x - 4)(x + 4) - 7(x - 4)(x + 4)
= x(x^2 - 16) - 7(x^2 - 16)
= x^3 - 16x - 7x^2 + 114
= x^3 - 7x^2 - 16x + 112
