Answer:
B
X= 7.5
Y= -5
Step-by-step explanation:
In systems of equations, the goal is to add both of the equations together so it cancels one of the variables and you solve for that variable. Before you add they together, you multiply one of the equations by a negative number so when you add them together one of the numbers with x or y cancel.

Answer: Here you go hope this helps
If a line is drawn through (twenty, seventy) and (twenty-five, sixty), then you can use the points in getting the equation.
Slope is = (60-70)/(25-20) = -2
Using the two-point slope form, y – y1 = m(x – x1)
y – 70 = -2(x – 20)
y – 70 = -2x + 40
y = -2x + 110

Answer:
i think the answer is A
Step-by-step explanation:
The number of ways is 497420
The ways can the team assign field positions to 9 of the 22 players, putting each of the 9 selected players in a position he can play, and ensuring that all 9 field positions are filled is
A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter. In combinations, you can select the items in any order.
22C9 = 22! /(9!*13!) = 497420
Thus, In 497420 ways the team assign field positions to 9 of the 22 players, putting each of the 9 selected players in a position he can play, and ensuring that all 9 field positions are filled.
