I think the equation would be x^2 + y^2 + Dx + Ey + F = 0

Arisa [49]

We can put in 6 - 2x for y:

2x + y = 6
2x +(6 - 2x) = 6
2x + 6 - 2x = 6
6 = 6

Since this statement is true:
x and y are all real numbers.

Hope this helps!

Help I don’t understand and I need this Done as soon as possible

Answer:

y - 7 = -1/4(x-4)

Step-by-step explanation:

point slope is y-y₁=m(x-x₁)

(4, 7) and (8, 6)

I like to put it in the slope-intercept form first

so... 6 - 7/ 8-4 = -1/4 (slope)

6 = -1/4(8) + b

6/(-2) = -2/(-2) + b

-3 = b

so... y=-1/4x + -3

plug it in to point slope form

y - 7 = -1/4(x-4)

hopefully that made sense :)

The lengths of the sides of a rectangle are 18cm by 3m. Express the area of the rectangle in square decametres.

lubasha [3.4K]

For this case we have that by definition, the area of a rectangle is given by:

$A = b * h$

Where:

b: It is the base of the rectangle

h: It is the height of the rectangle

By definition we have to:

1 meter equals 0.1 decameters

1 centimeter equals 0.001 decameters

According to the data of the statement we have:

$b = 18 \ cm * \frac {0.001} {1} * \frac {decametres.} {cm} = 0.018 \ decameters.\\h = 3m * \frac {0.1} {1} * \frac {decameters} {m} = 0.3 \ decameters.$
