Answer:
20
Step-by-step explanation:
If lines m and n are parallel, then the labelled angles would be considered alternate exterior angles. By definition, such angles are of the same value.
Thus, we set the two expressions of 4x - 23 and 2x + 17 equal:
4x - 23 = 2x + 17
Subtract 2x from both sides and add 23 to both sides:
2x = 23 + 17 = 40
Divide by 2:
x = 40/2 = 20
The answer is thus 20.

Answer:
y = 40 + 0.35x
y = 50 + 0.1x
Step-by-step explanation:
Talk A Lot Company
$40 for 600 mins
$0.35 for each extra min
Total cost = y
Number of extra minutes after 600 mins = x
y = 40 + 0.35x
Chat Away Company
$50 for 600 mins
$0.10 for each extra mins
Total cost = y
Number of extra minutes after 600 mins = x
y = 50 + 0.1x

The question is obscure, and incomplete. There are many ways we can interpret an equation, such as x = -2, or its alternate form: x + 2 = 0
This is a vertical line at x = -2, since the y variable will change in relation to its x-ordinate. Since, at all values of x it's constant, then the only changes we can make out here are its y counterparts.
The first attachment is the image of the equation.
Furthermore, we can geometrically describe this equation as a straight line. From the graph above, we can see that x = -2 is merely a vertical line with its root at x = -2.
We can also visualise and represent this on a number line, rooted at x = -2. The second attachment is a visual representation of x = -2 as a value on the number line.
