The product of 2 and a number minus 9 is 13
algol13
<h3><u>The value of the number is equal to 11.</u></h3>

2x - 9 = 13

<em><u>Add 9 to both sides.</u></em>

2x = 22

<em><u>Divide both sides by 2.</u></em>

x = 11

50 POINTS EACH HEEEEELP !!!!!
Phoenix [80]

Hello there,

The <em>answer is </em>A' (-3,2).

<h3>Step-by-step explanation:-</h3>

From the image shown on the xy-plane, the coordinate of point A is at (3,-2).

The rule for rotation by 180° about the origin is (x,y)→(-x, -y), where (x,y) is the coordinate of image and (-x, -y) is the coordinate of the resulting pre-image.

Given the coordinate point A(3,-2), if this coordinate is rotated 180°, the resulting point A' will be located at (-3,-(-2)) = (-3,2).

Therefore, the answer will be <u>A'(-3,2)</u>

We take the equation <span>d = -16t^2+12t</span> and subtract d from both sides to get
                                         0<span> = -16t^2+12t - d
We apply the quadratic formula to solve for t. With a = -16, b = 12, c = -d, we have
                                         t = [ -(12) </span><span>± √( 12^2 - 4(-16)(-d) ) ] / [2 * -16]</span>
                                           = [- 12 ± √(144-64d) ] / (-32)
                                           = [- 12 ± √16(9-4d)] / (-32)
                                           = [- 12 ± 4√(9-4d)] / (-32)
                                           = 3/8 ±√(9-4d) / 8
The answer to your question is t = 3/8 ±√(9-4d) / 8
