Y=(2-x) (1+3x)
This is vertical. and that should be 4x=1
The way you put the question in is a little confusing but what I got was 6 times 2 equals 12 but I may be wrong I apologize if my answer is wrong.
0.037037 is what 1/27 is in decimal form
Answer:
18 is 90% of 20
Step-by-step explanation:
an easy way to do this is 18/20
We know that
if two lines are parallel
then
the slopes are the same
we have
<span>15x - 16y = 1
solve for y
16y=15x-1
y=(15/16)x-(1/16)
m=15/16
case A)
</span><span>16x - 15y = 1
15y=16x-1
y=(16/15)x-(1/15)
m=16/15------> is not equal to 15/16
case B)
</span><span>15x + 16y = 1
</span>16y=1-15x
y=(1/16)-(15/16)x
m=-15/16-------> is not equal to 15/16
case C)
<span>y = (15/16) x - 7
m=15/16---------> is equal to 15/16
so
this equation is parallel to </span><span>15x - 16y = 1
</span>
case D)
<span>y = (16/15) x - 7
m=16/15-------> is not equal to 15/16
therefore
the answer is the option
</span><span>C y = (15/16) x - 7</span>
