Answer:
5
Step-by-step explanation:
In y=mx+b, y is the intercept with the y axis.
Check the picture below.
now, if AC is that much, recall, BD is the midsegment, thus AB = BC, so AB is just one of the equal halves of AC, so, AB is AC/2.
Answer:
The vertex is at (-1, -4).
Step-by-step explanation:
Y=4x2+8x Covert to vertex form:
y = 4(x^2 + 2x)
y = 4[(x + 1)^2 - 1)
= 4(x + 1)^2 - 4
The vertex is at (-1, -4).
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 = 
Answer:
$3000
Step-by-step explanation:
P = $2500
R = 2%
T = 10yrs
I = ?
I = PRT/100
I = (2500×2×10)/100
I = 50,000/100
I = $500
The final value = 2500 + 500
= $3000
