Answer:
Sometimes
Step-by-step explanation:
When x is a nonzero integer, then x can be
If x is negative, then is positive (multiplying negative number by -3 you get positive number).
If x is positive, then is negative (multiplying positive number by -3 you get negative number).
So, the statement "When x is a nonzero integer, the quantity -3x will be negative" is sometimes true.
a = -2
<h3>Explanation:</h3>We want (5-a) to be 20 more than (6a-1). Then we can write ...
... (5-a) = (6a-1) +20
If we add (a-19) to both sides, we get
... -14 = 7a
... -2 = a . . . . . divide by 7

<em>Comment on the graph</em>
In the attached, we use the variable x, because this graphing calculator likes variables named x and y. We graph each expression and find the place where they both have the same value for the same value of x (the point of intersection). The value of the variable x at that point is -2, the solution we seek.
Answer:
The sale this month = 79
Step-by-step explanation:
Let the amount he needs to sell this month = x
Note that number of entries = number of months = 5
To maintain an average sales of 77, the amount of sale in month 5 is determined as follows:
