Step-by-step explanation:
1 : 2
Hamburger cheeseburger
(you add the 1 & 2 to make 3)
231÷3=77
1×77=77
2×77=154
77 : 154
Hamburger cheeseburger
Hope it make sense :-)
Answer:
Step-by-step explanation:
-y = -5x + 7
y = 5x - 7
perp.: -1/5
y - 2 = -1/5(x + 8)
y - 10/5 = -1/5x - 8/5
y = -1/5x + 2/5
At Gino's you pay $16 plus $8 per pizza.
At Venetian's you pay $24 plus $6 per pizza.
Let the number of pizzas be x.
At Gino's you pay 16 + 8x
At Venetian's you pay 24 + 6x
Set the two costs equal and solve for x to find out the number of pizzas for which both costs are the same.
16 + 8x = 24 + 6x
16 + 2x = 24
2x = 8
x = 4
Each place gives you a free pizza.
4 pizzas plus the free pizza equals 5 pizzas.
If you need 5 pizzas (including the free one), both parlors cost the same.
If you need fewer than 5 pizzas, use Gino's.
If you need more than 5 pizzas, use Venetian's.
For the 3 you multiply the equations of f(x) and g(x) by each other and you do that by foiling then you combine like terms. After that the terms A, B,C D, and E are in the answer which is...
