Answer:
O 3x+12
Step-by-step explanation:
3(x + 4) = (3 · x) + (3 · 4)
= 3x + 12
(1) C = 15x + 40000 ...............because it cost $15 to produce each CD with a one-time cost of $40,000
(2) R = 59x ......................because each CD will sell for $59
(3) P = R - C → P = 59x - (15x + 40000) → P = 44x - 40000
(4) 44x = 40000 → x = 909 ........ They must sell 909 in order to break even

1. For y, I think that refers to the first picture attached. As you can see, each side of the triangle have the same short line drawn across it. It means that they are equal in length. That means the triangle is equilateral, which means each interior angle is 60°. Thus,
60 = 5y + 10
5y = 60 - 10
5y = 50
y = 50/5 =<em> 10</em>
2. As you can see in the second picture attached, Angles B and C are equal. That also means that their respective opposite sides are equal. So,
8x - 4 = 5x + 11
8x - 5x = 11 + 4
3x = 15
x = 15/3 = 5
Consequently,
BC = 4x - 2
BC = 4(5) - 2 = <em>18</em>
The system of equations does not have a solution.
For example, imagine these two equations y = x + 7 and y = x + 9
Now subsitute y in the second equation with the value from the first equation:
x + 7 = x + 9
x - x + 7 = 9
0 + 7 = 9
7 = 9.
That happens because the equations represent parallel lines, which do not have a common pair of points.
