Answer:
B.25$
Step-by-step explanation:
to make the money less one of the freinds will carry 9kg and the other 12 kg the last one carries the left luggage weighing 7kg and 6kg which add up to 13kg.
the first freind won't pay anything as he is passing 9kg luggage
the second will pay : 12-10 =2 so 2kg*5$=10$
the last freind will pay 13-10=3 so 3kg*5$=15$
to find the total money the pay we will add 10$ and 15$ which became 25$.
hope this helped.

Answer:
Step-by-step explanation:
This is a reflection over x-axis.
Answer:

Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
The product of the gradients of perpendicular lines is -1.
Gradient of given line= 3.
(Gradient of line)(3)= -1
3m= -1
m= 
subst. m=
into the equation:

To find the value of c, substitute a coordinate.
When x=0, y=4,

Thus the equation of the line is
.
