Answer:

1). 6x - 14 2). y = 1x + 1 3). y = -4x + 22 4).y = -7/2x + 51/2

Step-by-step explanation:

1). y2 - y1 / x2 - x1 4 - (-2) / 3-2 = 6

y = 6x + b 4 = 6(3) + b 4 = 18 + b -14 = b

y = 6x - 14

2). 2 - (-2) / 1 - (-3) = 1

y = 1x + b 2 = 1(1) + b 2 = 1 + b 1 = b

y = 1x + 1

3). 2 - 6 / 5 - 4 = -4

y = -4x + b 6 = -4(4) + b 6 = -16 + b 22 = b

y = -4x + 22

4). 1 - 8 / 7 - 5 = -7/2

y = -7/2x + 51/2

Brook makes this conjecture: Because the angles are equal, the proportion of area of each sector relative to the area of the giv

AnnZ [28]

Answer:

The Brooks conjecture is true as the proportion of the area of a sector to the area of a circle is only dependent on the angle.

Step-by-step explanation:

The area of a sector for a radius r and an angle θ is given as

$\Delta Sector=\dfrac{1}{2}r^2\theta$

Whereas the area of a circle for a radius r is given as

$\Delta Circle=\pi r^2$

Now the ratio is given as

$\dfrac{\Delta Sector}{\Delta Circle}=\dfrac{\dfrac{1}{2}r^2\theta}{\pi r^2}$

Here as r is the radius of the circle and it is the same therefore the above ratio is simplified to

$\dfrac{\Delta Sector}{\Delta Circle}=\dfrac{\theta}{2\pi }$

Here as π is constant the only variable here is θ. Thus according to Brooks conjecture when the angles are equal, the proportion of area of each sector relative to the area of the given circle is also equal is true.

I forgot how to divide fractions properly. please send help.

Mamont248 [21]

Answer:

2.5 or 10/4

Step-by-step explanation:

2÷4/5

Integers can be fractions. Which are just the summation of equal parts. So integers can be written in any fractional form as you like,

2/1÷4/5

But turning your fraction into an integer is not enough to divide, you must first use the reciprocal form of your dividend. and then you multiply to obtain your answer. (The reason is that division is multiplication of the reciprocal)

2/1×5/4

And tadaa! you get your answer

10/4

You can also simplify it!
