Points E(-1, -2) and F(4, -2) are the vertices of a square. Give the coordinates of three possible pairs of points for the other

777dan777 [17]

The vertices of a square are its endpoints

The coordinates of the other pairs are: (-1, 3), (4, 3) and (-1, -7), (4, -7)

The given parameters are:

$\mathbf{E = (-1,-2)}$

$\mathbf{F = (4,-2)}$

Calculate the distance EF

$\mathbf{EF = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}}$

So, we have:

$\mathbf{EF = \sqrt{(-1 - 4)^2 + (-2 - -2)^2}}$

$\mathbf{EF = \sqrt{25}}$

$\mathbf{EF = 5}$

Add 5 to the y-coordinates of E and F

$\mathbf{C = (-1,-2+5)}$

$\mathbf{C = (-1,3)}$

$\mathbf{D = (4,-2+5)}$

$\mathbf{D = (4,3)}$

Subtract 5 to the y-coordinates of E and F

$\mathbf{C = (-1,-2-5)}$

$\mathbf{C = (-1,-7)}$

$\mathbf{D = (4,-2-5)}$

$\mathbf{D = (4,-7)}$

Hence, the coordinates of the other pairs are: (-1, 3), (4, 3) and (-1, -7), (4, -7)

There is no third pair

Which function is the inverse of f(x) = -5x-4?

tankabanditka [31]

Step-by-step explanation:

$f(x) = - 5x - 4$

$\:$

<u>Inverse</u>

$y = - 5x - 4$

$x = - 5y - 4$

$x + 4 = - 5y$

$y = - \frac{(x + 4)}{5}$

${f}^{ - 1} (x) = - \frac{(x + 4)}{5}$

Answer the following questions CORRECTLY I will know if this is wrong. I WILL REPORT ANY INCORRECT ANSWERS!

valkas [14]

Answer by JKismyhusbandbae: expression 2 and expression 1

Look at the four expressions. Simplify any expressions that can be simplified to see which two are equivalent.

8v × 30v = ( 8 × 30) × ( v × v) = $240v^2$

Since expression 2 can be simplified to expression 1, they are equivalent.

What is -5.8+(-2.5)

Scilla [17]

-5.8 + (-2.5) = -8.3

since both the number are negative you simply add the numbers and use the negative sign.
