Figure MNPQR will be reflected across the x-axis to create figure M'N'P'Q'R'. Which rule describes this transformation? A.(x,y)

kolbaska11 [484]

Answer:

D.(x,y) → (x,-y)

Step-by-step explanation:

If it is reflected across the X-axis, then the X variable will stay the same and the Y variable will change.

I hope this helps!! Good luck!!

(Sorry if I'm wrong! It's kinda awkward because it is placed in the second quadrant instead of the first.)

Someone help please

Use ax^2 + bx + c = 0

ac = -8
b = 2

The factors are 4 and -2.
Plug them into the equation:

x^2 + 4x - 2x - 8

Then factorise it:

x ( x + 4) - 2 (x + 4)

so m = 4

(x + 4)^2

Question (in need of help)

mr Goodwill [35]

<h3><u>Required</u><u> Answer</u><u>:</u><u>-</u></h3>

This is an right angle ∆ and the side lengths containing a right angle are 9 and 11.

By Pythagoras theoram,

${p}^{2} + {b}^{2} = {h}^{2}$

where p is the perpendicular, b is the base and h is the hypotenuse.

Plugging the values,

${9}^{2} + {11}^{2} = {h}^{2}$

Then,

$h = \sqrt{ {9}^{2} + {11}^{2} }$

$h = 14.12(approx.)$

<h3><u>Hence:</u><u>-</u></h3>

The x of the right angled ∆ = <u>1</u><u>4</u><u>.</u><u>1</u><u>2</u>
