Answer:

x=4

ME=9

AM=18

AE=27

Because m in the midpoint ME is double AM

2(4x-7)=5x-2 4(4)-7 5(4)-2 18+9

8x-14=5x-2 16-7 20-2 =27

<u>-5x -5x</u> =9 =18

3x-14=-2

<u> +14 +14</u>

<u>3x</u>=<u>12</u>

Which function passes through the points (2,3) and (4,4)?

Pie

A(2;3), B(4;4)
$y=ax+b$
$a=\dfrac{4-3}{4-2}=\dfrac{1}{2}$
$3=\dfrac{1}{2}*2+b$
$3=1+b$
$b=2$

$y=\dfrac{1}{2}x+2$

for a singing contest in which 42,000 votes were cast, the winner received 3/5 of the votes. How many votes did the winner not r

Xelga [282]

There are two ways:

1. (42,000 * 3)/5 =

126000/5 =

25200

2. 42000/5 =

8400*3 =

25200

Now subtract 25200 from original

42000 - 25200 = 16800

16800 votes were not for the winner
