What is the input value for which the statement f(x) = g(x) is true?
Murljashka [212]

Answer: According with the graph, the input value for which the statement f(x)=g(x) is true (the value of "x" where the graph intersect) is 1.5 (third option).


Solution

The input value for which the statement f(x) = g(x) is true, is the value of "x" where the graph of the two functions intersect. Accordind with the graph, the two functions f(x) and g(x) intersect at x between 1 and 2, approximately at x=1.5

Can anyone help me to understand how to solve coordinate proofs in Geometry?????
nataly862011 [7]

The coordinate proof is a proof of a geometric theorem which uses "generalized" points on the Cartesian Plane to make an argument.The method usually involves assigning variables to the coordinates of one or more points, and then using these variables in the midpoint or distance formulas .For example, the following is a coordinate proof of the Triangle Midsegment Theorem , which states that the segment connecting the midpoints of two sides of a triangle is parallel to the third side and exactly half the length.Without loss of generality, we can assume that one side of the triangle lies on the xx -axis with one vertex at (0,0)(0,0) and the other vertex at(a,0)(a,0).Let the third vertex have the coordinates (b,c)(b,c) . We can assume without loss of generality that this third vertex lies in the first quadrant. (If it doesn't, you can just reflect the triangle over the xx - and/or yy -axis until it does.)

Example:

To Prove: XY¯¯¯¯¯¯XY¯ is parallel to PR¯¯¯¯¯PR¯ and

<span><span>XY=<span>12</span>PR</span><span>XY=<span>12</span>PR</span></span>

Proof:

Using the midpoint formula , the coordinates of the midpoints XX and YY are

<span><span><span>X<span>(<span><span><span>0+b</span>2</span>,<span><span>0+c</span>2</span></span>)</span>=X<span>(<span><span>b2</span>,<span>c2</span></span>)</span></span><span>Y<span>(<span><span><span>a+b</span>2</span>,<span><span>0+c</span>2</span></span>)</span>=Y<span>(<span><span><span>a+b</span>2</span>,<span>c2</span></span>)</span></span></span><span><span>X<span>(<span><span><span>0+b</span>2</span>,<span><span>0+c</span>2</span></span>)</span>=X<span>(<span><span>b2</span>,<span>c2</span></span>)</span></span><span>Y<span>(<span><span><span>a+b</span>2</span>,<span><span>0+c</span>2</span></span>)</span>=Y<span>(<span><span><span>a+b</span>2</span>,<span>c2</span></span>)</span></span></span></span>

First note that the <span>slope </span>is <span>00</span> , since

<span><span><span>m=<span>riserun</span></span><span>     =<span><span>(<span><span>c2</span>−<span>c2</span></span>)</span><span>(<span><span>b2</span>−<span>(<span><span>a+b</span>2</span>)</span></span>)</span></span></span><span>     =<span>0<span>(<span><span>b2</span>−<span>(<span><span>a+b</span>2</span>)</span></span>)</span></span></span><span>     =0</span></span><span><span>m=<span>riserun</span></span><span>     =<span><span>(<span><span>c2</span>−<span>c2</span></span>)</span><span>(<span><span>b2</span>−<span>(<span><span>a+b</span>2</span>)</span></span>)</span></span></span><span>     =<span>0<span>(<span><span>b2</span>−<span>(<span><span>a+b</span>2</span>)</span></span>)</span></span></span><span>     =0</span></span></span>

So, <span><span><span>XY</span><span>¯¯¯¯¯¯</span></span><span><span>XY</span>¯</span></span> is parallel to <span><span><span>PR</span><span>¯¯¯¯¯</span></span><span><span>PR</span>¯</span></span> .

Now, compare the lengths of the two segments.

<span><span><span>XY=<span><span>a+b</span>2</span>−<span>b2</span></span><span>        =<span>a2</span></span><span>PR=a−0</span><span>        =a</span></span><span><span>XY=<span><span>a+b</span>2</span>−<span>b2</span></span><span>        =<span>a2</span></span><span>PR=a−0</span><span>        =a</span></span></span>

So,

<span><span>XY=<span>12</span>PR</span><span>XY=<span>12</span>PR</span></span>

Thanks to google for example


hope this helps

The bulletin board is 6 feet wide and 4 feet tall.  The border is 3 inches wide.  What are the dimensions inside the border?
Alexxandr [17]
Because the boarder goes around all edges, 6 in must be subtracted from 6ft and 4ft.
6ft - 6in = 5.5 ft
4ft - 6in = 3.5 ft 
Area of the bulletin board: (5.5)(3.5) = 19.25 ft
