Answer:

3/5x + 3/8

Step-by-step explanation:

2/5x + 5/8 + 1/5x - 1/4

1. Combine like terms so now u have

3/5x + <u><em>3/8 </em></u>

In case you want to know how I got 3/8

You want a common denominator so

from  5/8 + 1/4, make both denominator 8

so 1 *2/ 4* 2

so now you converted the 1/4 to 2/8

So then 5/8 - 2/8 gives u 3/8 and that's how i got 3/8

Hope this helped!

The number of eligible voters who cast ballots on election day is referred to as the:_____-.
kozerog [31]

The number of eligible voters who cast ballots on election day is referred to as the <u>VOTER TURNOUT.</u>

<u></u>

<h3>What is the voter turnout?</h3>

This refers to the number of a nation's registered voters who actually vote for various positions on election day.

This figure is important because it shows just how much of the population has faith in the electoral system and so trust it to count their vote.

Pleaseeeee help me. i really need it.
deff fn [24]

comparing the relation given

thus y= -2x +1 to the general equation of a line

where y= mx + c

where m is the gradient and c is the intercept on the y-axis.

from the question, the gradient is -2 and since the line is perpendicular, the gradient is given as

\frac{ - 1}{m}

so substituting the value of m in to the equation

\frac{ - 1}{ - 2}

=

\frac{1}{2}

as the gradient

equation of line is given by

y - y1 = m( x-x1)

from the question y1= -2 and x1=1

substitute them

y-(-2) = 1/2 (x -1)

y+2 =1/2 (x-1)

multiplying through by 2

2 (y+2) = x-1

2y +4 = x-1

2y =x-1-4

2y =x-5

x -2y -5 = 0

therefore the equation for the line is x-2y -5=0

Write the equation for 5x + 2y = 3 in slope-intercept form.
Vikki [24]

Answer:

B. y = -5/2x +3/2

Step-by-step explanation:

5x + 2y = 3

We want to get this in the form

y = mx +b where m is the slope and b is the y intercept

Subtract 5x from each side

5x -5x+ 2y =-5x+ 3

2y = -5x+3

Divide by 2

2y/2 = -5x/2 +3/2

y = -5/2 x +3/2

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
