Answer:
26
Step-by-step explanation:
The sum of angles in a triangle is 180 degrees, use this and set up an equation;
x + ( 4x -5 ) + 55 = 180
Simplify
x + ( 4x - 5 ) + 55 = 180
5x + 50 = 180
Inverse operations;
5x + 50 = 180
-50 - 50
5x = 130
/5 /5
x = 26
Hello!
To find the line parallel to the line y = -2/3x + 1 and passing through the point (-6, -1), we will need to know that if two lines are parallel, then their slopes are equivalent to each other.
Since we are given the slope, we need to find the y-intercept of the line. We can find the y-intercept by substituting the point (-6, -1) into a new equation with the slope of m = -2/3. Remember that slope-intercept form is y = mx + b.
y = -2/3x + b (substitute the ordered pair)
-1 = -2/3(-6) + b
-1 = 4 + b (subtract 4 from both sides)
-5 = b
Therefore, the equation of the line passing through the point (-6, -1) and parallel to y = -2/3x + 1 is y = -2/3x - 5.

Answer:
The correct answer is 14000 units.
Step-by-step explanation:
Cost function of x number of units sold is given by C(x) = 12x + 56000
Revenue function is given by R(x) = 16x
We need to find the number of units sold in order to break even. That invariably means we need to find the number of units at which the cost is equal to revenue or the profit is zero.
Thus profit π = R(x) - C(x) = 16x - 12x - 56000 and this is supposed to be equal to zero.
∴ 4x - 56000 = 0
⇒ 4x = 56000
⇒ x = 14000
Thus 14000 units of the goods needs to be sold to break even.
