Let: x = number of copies sold
We can formulate the following equation to solve for x:
1.50x - 0.9x - 600 = 0
x = 1000
Therefore, the club must sell 1000 copies to break even. Among the choices, the correct answer is A.
X = 3 and x = 4 will make the polynomial = 0
answer
C. 3 and 4
A line parallel to your equation has the same slope, so it should be in the form:
y = (-3/2)x + b
To figure what "b" has to be, plug in the point (4,0) and solve:
0 = (-3/2)*4 + b
0 = -6 + b
6 = b
So the equation of the line is:
y = (-3/2)x + 6
Answers:
1. P=3
Step by step:
P-5=-2 -move the constant to the right hand side and change its sign
P=-2+5 - calculate the sum
P=3
2. W=-2.8
Step by step:
W+13.2=10.4 - move the constant tot he right hand side and change its sign
W=10.4-13.3 - calculate the difference
W=-2.8
3. X=2/3
Step by step:
X-5/6=-1/6 - move the constant to the rig hand side and change its sign
X=-1/6+5/6 - calculate the sum
X=2/3
Exterior angle = 360/25 = 14.4 degrees
internal angle = 180-14.4 = 165.6 degrees
sum of all the angles = 165.6*25 = 4140 degrees answer
