Answer:
Step-by-step explanation:
Bring the like terms together
5x + 22 - 6x -23 = 5x - 6x + 22 -23 {now, add/subtract the like terms}
= -x -1
C=x.19+.25
C means the total cost
X means the extra minutes
Answer:
350
Step-by-step explanation:
5x7x10=350
slope = difference in y / difference in x
slope = 12 -11 / 2 -6
slope = 1 / -4
slope = -1 / 4 or
-.25

<h2>
Explanation:</h2>
The vertex form of the equation of a parabola is given by the following form:

In this exercise, we have the following equation:

From here, we can conclude that:

Since the leading coefficient is less than zero, the parabola open downward. So, the graph is shown below and the vertex has been indicated.
