Which of the following points lies on the line y=x? (-4,4) (2,-2) (-4,-4) -2,2

marshall27 [118]

The answer is (-4,-4) because y has to equal x, the first -4 is the x and the second one is the y

a system of equations is shown below: equation a: 2c = d − 8 equation b: c = 3d 8 which of the following steps should be perform

Fofino [41]

If you would like to know which of the following steps should be performed to eliminate variable d first, you can find this using the following steps:

equation a: 2c = d - 8 /*(-3)
equation b: c = 3d + 8
__________________
-6c = -3d + 24
c = 3d + 8
__________________
-6c + c = -3d + 24 + 3d + 8
-5c = 32
5c = -32
c = -32/5

The correct result would be: multiply equation a by −3.

Find the distance between the two points in simplest radical form. (1, -7) and (7,0)

denis23 [38]

Answer:

The distance between the two given points is equal to √85.

Step-by-step explanation:

Let's recall what the distance formula is:

$\displaystyle \huge\math\boxed{d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2} }$

We are defined our two points as:

(x₁, y₁) → (1, -7)
(x₂, y₂) → (7, 0)

We can rewrite this into our different "variables":

x₁ = 1
y₁ = -7
x₂ = 7
y₂ = 0

Now given our distance formula and our variables, we can find the distance between the two points:

$\displaystyle\huge\begin{aligned}d & = \sqrt{(1 - 7)^2 + (7 - 0)^2} \\& = \sqrt{(-6)^2 + (7)^2} \\& = \sqrt{36 + 49} \\& = \math\boxed{\sqrt{85}} \\\end{aligned}$

∴ since the radical is already in its simplest form, our distance between the two points is equal to √85.

Hope this helps!
