Answer:
a = 14.9
b = 75
c = 22.5
Step-by-step explanation:
The equation given is just the law of sines converted into terms of x.
Answer:
(C) (2, -2)
Step-by-step explanation:
Given the linear equation: 
A second linear equation is given by the table:
Clearly, this is a graph of y=-x as each y-value is a negative of its x-value.
Therefore if:
Recall: y=-x
Therefore: y= -2
Therefore, a solution to the system of equations is (2, -2)
Answer:
Sorry but the correct answer is (x+3)2+(y−1)2=81
Step-by-step explanation:
Because the radius squared is the answer of the equation
Let Peter's hit be x and Alice's runs be y.
x = 2(y - 6) . . . (1)
x + y = 18 . . . (2)
Putting (1) into (2) gives,
2y - 12 + y = 18
3y = 18 + 12 = 30
y = 30/3 = 10
x = 2(10 - 6) = 2(4) = 8
Therefore, Peter hit 8 home runs and Alice hit 10 home runs.
