The coordinates for three points of a rectangle are (2, 6) (2, 9) and (8, 6). What is the coordinate for the fourth point in the

saw5 [17]

Answer:

(8,9)

Step-by-step explanation:

Given

$A = (2,6)$

$B = (2,9)$

$C = (8,6)$

Required

Determine the 4th point

The coordinate point of a horizontal or a vertical rectangle is given as:

(x1,y1), (x2,y2), (x3,y3), (x4,y4)

Where:

$x_1 = x_2$ $x_3 = x_4$ $y_1 = y_3$ $y_2 = y_4$

So, we have:

$A = (2,6)$ --- $(x_1.y_1)$

$B = (2,9)$ ---- $(x_2.y_2)$

$C = (8,6)$ ---- $(x_3,y_3)$

Using the above equations:

$x_3 = x_4$ $=8$

$y_2 = y_4$ $= 9$

Hence, the coordinate of the 4th point is:

$(x_4,y_4) = (8,9)$

√8x^2 divided by √2x

Ghella [55]

Question: Simplify $\frac{\sqrt{8x^2}}{\sqrt{2x}}$ .

First off, you <em>never</em> want square roots on the bottom of a fraction, so let's multiply both sides by $\sqrt{2x}$ to get rid of it. All we have to do from there is simplify!

$\frac{\sqrt{8x^2}}{\sqrt{2x}}*\frac{\sqrt{2x}}{\sqrt{2x}}=\frac{\sqrt{8x^2}*\sqrt{2x}}{2x}}=\frac{\sqrt{16x^3}}{2x}=\frac{4x\sqrt{x}}{2x}=\boxed{2\sqrt{x}}$

This table gives a few (x,y) pairs of a line in the coordinate plane.

fomenos

Answer:

(-22,0)

explanation:

You subtract 10 from 8 and you get -2 and if you subtract 10 from -2 you get -12 so there for you are subtracting by 10 on the x-values so if you do -12 - 10 = -22 making your answer (-22,0).

Hope this helps (. ❛ ᴗ ❛.)
