Start by distributing
30x - 300 = 15x
add 300 to both sides
30x = 300 + 15x
subtract 15x from both sides
15x = 300
divide both side by 15
x = 20
<span> 6 over x minus 4 equals 4 over x
6/(x-4) = 4/x
4(x-4) = 6x
4x - 16 = 6x
2x = -16
x = -8
</span>Verify:
6/(-8-4) = 4/-8
6/(-12) = 4/(-8)
-1/2 = -1/2

</span><span>B) x = −8, non-extraneous</span>
If she pays 5% a year for interest on a $5,000 loan she will pay $1,250
$225 a year for 5 years
Y= 3/4x - 2 (-2,10)= (x1,y1)
The slope is -4/3 of the perpendicular line:
Then:
y-y1=m(x-x1)
y-10=(-4/3)(x+2)
y=-(4/3)x -8/3 +10
y= -(4/3)x +22/3 (That's the answer)
