El opusesto sera lo contrario,si es negativo de convertira a postivo y si es positivo de convierte ah negativo.
Answer:
Option A is the correct choice.
Step-by-step explanation:
We have been given the system of linear equations written by Draco. We are asked to find Draco's error.
Let us form a system of equations using our given information.
Let m represent the price of one muffin and b represent the cost of one bagel.
We are told that in one hour a bakery sold five muffins and nine bagels for a total of $25.50. We can represent this information in an equation as:
The next hour the bakery sold three muffins and 12 bagels for a total of $28.50. We can represent this information in an equation as:
Now let us see system of equations written by Draco.
We can see that Draco has set the price of 5 muffins and 9 bagels equal to $28.50, which is the price of 3 muffins and 12 bagels.
Therefore, Draco should have set the first equation equal to 25.50 and the second equation equal to 28.50. The correct choice is option A.

Answer: 34.1754
Step-by-step explanation:
Answer:
y intercept: (0,3)
x intercept (3/7,0)
Step-by-step explanation:
The slope intercept form is y=mx+b, where m represents the slope of a line and b represents the y intercept. This makes the y intercept easy, just (0,3). The x intercept can be found by setting y to 0. Then, you are left with:
0=-7x+3
7x=3
x=3/7
And so the x intercept is (3/7,0). Hope this helps!
