Answer:

$\sqrt{x}$ = -1 - $\sqrt{x-2}$

x = 1 -2 $\sqrt{x-2}$ + (x -2)

0 = -1 - 2 $\sqrt{x-2}$

- $\frac{1}{2}$ = $\sqrt{x-2}$

$\frac{1}{4}$ = x - 2

x = ±9/4

9/4 does not satisfy the equation.. this problem has no real answer solution

The vertices of quadrilateral MNPQ are M(−3,−2),N(−1,4),P(2,4), and Q(4,−2). Translate quadrilateral MNPQ using the vector ⟨3,−4

muminat

Answer:

see explanation

Step-by-step explanation:

A translation using the vector < 3, - 4 > , means

Add 3 to the x- coordinate and subtract 4 from the y- coordinate, so

M (- 3, - 2 ) → M' (- 3 + 3, - 2 - 4 ) → M' (0, - 6 )

N (- 1, 4 ) → N' (- 1 + 3, 4 - 4 ) → N' (2, 0 )

P (2, 4 ) → P' (2 + 3, 4 - 4 ) → P' (5, 0 )

Q (4, - 2 ) → Q' (4 + 3, - 2 - 4 ) → (7, - 6 )
