Answer:

y = -3x² - 3x + 6

Step-by-step explanation:

main formula: r×(x² - (a + b)x + ab) = y

r×(x² - (-2 + 1)x -2×1) =y

r×(x² +x -2) = y

by using the point (0,6) →

r×(0² + 0 -2) = 6

r×-2 = 6

r= -3

so

y= -3x² -3x +6

Answer:

The coordinates of B are: (a, b)=(-2, -6)

Step-by-step explanation:

Let (a, b) be the coordinates of the point 'B'.

As

The midpoint of AB is M(-4, 0)

The coordinates of A are (-6, 6)

The midpoint (x,y) of line joining points (x₁, x₂) and (y₁, y₂)

x=\frac{x_1+x_2}{2},\:y=\frac{y_1+y_2}{2}

-4 = (-6+a)/2  and  0 = (6+b)/2

-8=-6+a          

-8+6=a                  

a=-2

0=(6+b)/2

0=6+b

b=-6

Therefore, the coordinates of B are: (a, b)=(-2, -6)

(|5 - 3x | - 1) - ( 1 - 3x ) = 0
Basile [38]

(| 5 - 3x | - 1) - (1 - 3x) = 0

|5 - 3x| - 1 - 1 + 3x = 0

|5 - 3x| - 2 + 3x = 0

1) (5 - 3x) - 2 + 3x = 0, if 5 - 3x >= 0

3 = 0. has no solutions

2) -(5 - 3x) - 2 + 3x = 0, if 5 - 3x < 0

-5 + 3x - 2 + 3x = 0

6x = 7

x = 7/6

5 - 3x < 0

-3x < -5

x > 5/3.

has no solutions
