50 might be the answer because 12÷6=2 so I just multiplied 15×2 and that equaled my answer, 50
We know that
(ad)/(bd)=d/d time a/b=a/b since d's cancel
also
if a/b=c/d in simplest form, then a=c and b=d
we have
p/(x^2-5x+6)=(x+4)/(x-2)
therefor
p/(x^2-5x+6)=d/d times (x+4)/(x-2)
p/(x^2-5x+6)=d(x+4)/d(x-2)
therefor
p=d(x+4) and
x^2-5x+6=d(x-2)
we can solve last one
factor
(x-6)(x+1)=d(x-2)
divide both sides by (x-2)
[(x-6)(x+1)]/(x-2)=d
sub
p=d(x+4)
p=([(x-6)(x+1)]/(x-2))(x+4)
Answer: -7

Step-by-step explanation:
Answer:
$15
Step-by-step explanation:
Can't help you with the drop down, as we need to know the info for Station A to be able to compare it with Station B, however, the cost for charging a car at Station B for 4 hours is:
use f(x) = 3x + 3 as the value of x = 4 falls in this function's interval
So f(4) = (3 x 4) + 3 = 15
So it will cost $15 for a car to charge for 4 hours at Station B.
