Answer:
7.7- 3.51 goes to 8-4=4
3.5 -1.2 goes to 4-1 =3
22.78 - 14.12 goes to 23 - 14=9
16.208 - 3.652 goes to 16- 4= 12
F(-4) = 3 x 2 - 5(-4) + 4
3x2= 6
-5(-4)= 20
6-20= -14
-14+4= -10
f(-4) = -10
Answer:
x = 0
Step-by-step explanation:
The equation of a vertical line parallel to the y- axis is
x = c
where c is the value of the x- coordinates the line passes through
The only equation in this form is
x = 0 ( the equation of the y- axis )
Answer:

Step-by-step explanation:
Entrance fee per head = d
Entrance fee for the 5 friends = 5*d = 5d
Booklet of ride ticket per head = 2.5d
Booklet of ride ticket for the 5 friends = 5(2.5d)
Meal ticket per head = d - 4
Meal ticket for the 5 friends = 5(d - 4)
Total amount paid altogether by the five friends = 
From this breakdown above, the total amount paid by the 5 friends for their meal tickets =
