Answer:

slope of r = -9/4

slope of Q = 4/9

Step-by-step explanation:

x1 y1 x2 y2

10 6 1 2

(Y2-Y1) (2)-(6)= -4 ΔY -4

(X2-X1) (1)-(10)= -9 ΔX -9

slope= 4/9

A compound used to remove permanent

Zolol [24]

Answer:

Well by looking at the products,it must be sodium bicarbonate (NaHCO3)

Step-by-step explanation:

but then sodium bicarbonate does not remove permanent hardness of water,that compound is washing soda(Na2CO3) which should not be confused with NaHCO3. So as it would appear,the premise of the question is wrong but there is a compound that reacts with HCl to give those products

What is the area of the following?<br> Height: 3x2 - 2x - 6<br> (4x)<br> (4x)<br> (4x)

mestny [16]

The area of the rectangle shown is expressed as 4x² - 2x - 6

The diagram is attached below:

Area of a rectangle = Length * width

From the diagram;

Length = 4x - 6

Width = x+1

Substitute the given parameters into the formula as shown:

Area = 4x-6(x+1)

Area = 4x(x) + 4x (1) - 6x - 6

Area = 4x² + 4x - 6x - 6

Area = 4x² - 2x - 6

Hence the area of the rectangle shown is expressed as 4x² - 2x - 6
