Question:
Solve for x: . Fill in both values for x below. Write the greater value for x in the first column.
Answer:
and
are the values for x.
Explanation:
The equation is
Subtracting both sides by 7,
Dividing both sides by 12,
Now, we shall write the equation by removing modulus by adding plus and minus on the other side of the equation.
or
Solving the equation , we get,
or
Thus, the solutions are and
Answer:
- The y-intercept is - 372 and it means that if the manufacturers do not produce and sell any blenders they will have a loss of $ 372.
Explanation:
The polynomial that represents the function is:
Where the variable, x, represents the number of blenders produced and sold monthly, and P(x) is the monthly profit in dollars obtained for the sale of x blenders.
As for the question, the y-intercept is the point on the graph where the function crosses the y-axis, i.e. where the input of the function is x = 0.
Therefore, the y-intercept is the value of the function for x = 0, P(0), and it is found by substituting 0 for x in the polynomial function, which is shown next:
The meaning of this value is that the firm loses $372 when it does not produce and sell any blenders.
