Answer:

(-3, 18) ; (-1, 6)

Step-by-step explanation:

y = x^2-2x + 3

y = -6x

-6x = x^2 - 2x + 3

x^2 + 4x + 3 = 0

(x+3)(x+1) = 0

x = -3

x = -1

Solution 1

x= -1

y = 6

Solution 2

x= -3

y = 18

(a) The landscaper plans to put a fence around the entire yard. How many meters of fencing does she need? Show your work.

(b) The landscaper plans to create a rectangular garden that is the size of the actual yard. What is the area of the garden?

Answer:

28cm ; 48cm²

Step-by-step explanation:

From the diagram :

Length = 8cm

Width = 6cm

Meters of fencing required :

Perimeter of rectangle :

P = 2(length + Width)

P = 2 (8cm + 6cm)

P= 2(14cm)

P = 28 cm

2.)

Area of rectangle :

Length * width

8cm * 6cm

= 48cm²

The solution to the algebraic equation, −0.4x − 3.1 = 5.9, is: x = -22.5

Given the algebraic equation, −0.4x−3.1 = 5.9, to solve for x, follow the steps below:

−0.4x − 3.1 = 5.9

Add 3.1 to both sides

−0.4x − 3.1 + 3.1 = 5.9 + 3.1

-0.4x = 9

Divide both sides by -0.4

-0.4x/-0.4 = 9/-0.4

x = -22.5

Therefore, the solution to the algebraic equation, −0.4x − 3.1 = 5.9, is: x = -22.5
