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>

log rules
if no base is stared assume base 10
log_a(b)=c means a^c=b
log(a)+log(b)=log(ab)
if a^b=c^b and b=b then a=c
so
log(2x)+log(x)=2
log_10(2x^2)=2
10^2=2x^2
100=2x^
50=x^2
Answer:
Davide's age is 10.
L'età di Davide è 10.
Step-by-step explanation:
The average age of Aldo, Bruno, Carlo and Davide is 16 years.
I am going to say that:
x is Aldo's age.
y is Bruno's age.
z is Carlo's age.
w is Davide's age.
Average of the 4 is 16 years.
This means that:
If we do not consider Davide, the mean is 18. So
Replacing in the first equation:
Davide's age is 10.
L'età di Davide è 10.
Answer:
If you shoot the bullet off the back of the car , the bullet will still be moving away from you and the gun at 1,000 mph, but now the speed of the train will subtract from the speed of the bullet. Relative to the ground, the bullet will not be moving at all, and it will drop straight to the ground.
