Answer:

3x - y + 5 = 0

Step-by-step explanation:

When two points are given and the equation of the line passing through those points are asked we use two - point form to determine the equation of the line.

Two - point form: $ \frac{y - y_1}{y_2 - y_1} = \frac{x - x_1}{x_2 -x_1} $

Here the two points are: (2,11) & (-8,-19).

Let $ (x_1,y_1) = (2,11) $ and $ (x_2, y_2) = (-8,-19) $

Substituting in the formula we have:

$ \frac{y - 11}{-19 - 11} = \frac{x - 2}{-8 - 2} $

$ \implies \frac{y - 11}{-30} = \frac{x - 2}{-10} $

Simplifying we get:

y - 11 = 3x - 6

⇒                                       3x - y + 5 = 0

One half of the sum of a number and 10
garri49 [273]

Let's assume the number be x.

So, sum of a number and 10 can be written as x+10.

Now the given statement is "One half of the sum of a number and 10 ".

So, one half of x+10 can be written as \frac{1}{2} (x+10)

A sphere and a cube have equal surface areas. The length of one edge of the cube is 1.11 meters. What is the radius of the spher
Nady [450]

Answer:

  0.767 m

Step-by-step explanation:

The area of a cube of edge length s is given by ...

  A = 6s^2

The area of a sphere of radius r is given by ...

  A = 4πr^2

When these two are equal, we have ...

  6s^2 = 4πr^2

  r^2 = 6s^2/(4π)

  r = s·√(3/(2π)) ≈ s·0.690988

The radius of the sphere is about ...

  r ≈ 0.690899×1.11 m

  r ≈ 0.767 m . . . . approximate sphere radius
