Ariana and Emily are both standing in line at Papa Joe’s Pizza. Ariana orders 4 large cheese pizzas and 1 order of breadsticks.
1 answer:
The cost of 1 large pizza is $7.99 and cost of one breadstick is $2.50
Elimination method was used.
Step-by-step explanation:
Let,
Cost of one large pizza = x
Cost of one breadstick = y
According to given statement;
4x+y=34.46 Eqn 1
2x+y=18.48 Eqn 2
Subtracting Eqn 2 from Eqn 1
Dividing both sides by 2
Putting x=7.99 in Eqn 2
The cost of 1 large pizza is $7.99 and cost of one breadstick is $2.50
Elimination method was used.

The letter a represents the coefficient of
The absolute value of a (the number without the sign) controls how wide or narrow it is. If the absolute value is a fraction less than 1 the graph gets wider. The smaller the absolute value of the fraction the wider the graph gets.
If the absolute value of a is greater than 1 the graph gets narrower (it gets skinnier). The bigger the absolute value the narrower the graph.
So, if all the graphs look like a U (concave up) then the one with the smallest a is the one that is the widest.
The a also controls whether the graph is concave up or concave down. If a is negative
If a is negative the graph is concave down so any graph that is concave down has a smaller value of a than any graph that is concave up. However, if the graph is concave down the one with the smallest a would be the most narrow one.
So to find the one with the smallest a...
If they are all concave up (like a U) pick the widest one
and
If they are not all concave up pick the narrowest one that is concave down (looks like an upside down U)
