Answer:

True.

Step-by-step explanation:

This is 'less than' so the area below the line is shaded.

It is a dotted line because the solution does not contain points on the line as the inequality sign is < NOT ≤.

Answer:

First option: True.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

$y=mx+b$

Where "m" is the slope of the line and "b" is the y-intercept.

Given this inequality:

$y$

We know that the line is:

$y=2x -5$

Whose slope is 2 and the y-intercept is -5

The symbol "<" provided in the inequalty, indicates that the shaded region must be below the line and the line must be dotted. Therefore, the answer is: TRUE.

The bill at a restaurant came to $136.40.The customer decided to leave a 15% tip.What was the total bill including tip.

hjlf

Answer:

$156.86

Step-by-step explanation:

To calculate tip, you need to multiply the total bill by the percent tip you are going to leave. In this case the bill is $136.40, and the customer is going to leave a 15% tip. So, you would want to move the decimal place over to the left by 1, which you should get 13.64 as your number. Then divide it in half, which should give you 6.82. Now add 13.64 and 6.82 with the original bill price. If you don't add the 13.64 you would've forgotten the 10% part of the tip. At the end you should get $156.86 as your final bill.
