y = total cost
x = amount of toppings
z = # of patties
y = 4z + 0.75x
For one burger with 1 topping, the equation becomes y = 4 + 0.75
1 topping: $4.75
4 toppings: 4 + (0.75 x 4) = $7
6 toppings: 4 + (0.75 x 6) = $8.50
10 toppings: 4 + (0.75 x 10) = $11.50
Step-by-step explanation:
Question 5 answer:-
5 tickets for 12.50 is $2.50 each
8 tickets for20.16 is $2.52 each.
so, 5 tickets for $12.50 is the better deal
Answer:
Step-by-step explanation:
-5x - 1 = 2x + 6
-7x - 1 = 6
-7x = 7
x = -1
y = 2(-1) + 6
y = -2 + 6
y = 4
(-1, 4)
Answer:
The nth term will be:
Step-by-step explanation:
Given the sequence
-5, -15, -25, ...
An arithmetic sequence has a constant difference 'd' and is defined by

computing the differences of all the adjacent terms

The difference between all the adjacent terms is the same and equal to

The first element of the sequence is:

Thus, the nth term will be:

substituting the values
; 


Plug in n = 93 to determine the nth term



Therefore, the nth term will be:
Answer:
B
