1. Your total restaurant bill is _____. (1 point)

Lady_Fox [76]

First question:

Your total restaurant bill is the items you have purchased plus the sales tax and plus the tip (if there’s any). Sales tax is added to your purchase because this is tax imposed to the consumer and not to the buyer. The buyer is only required to collect this tax from the buyer.

Second question:

On a very cold morning, it was -7°F. As the day went on, the temperature rose 3 degrees each hour. Which equation shows the temp

wariber [46]

Answer:

The equation shows the temperature over time will be:

$y = 3x - 7$

Hence, option (C) is correct.

Step-by-step explanation:

We know that the slope-intercept form of the line equation is

$y=mx+b$

where m is the rate of change or slope and b is the y-intercept

Let 'y' be the temperature

Let 'x' be the time in the hour

Given that one very cold morning, it was -7°F.

Thus, the y-intercept = b = -7

Given that as the day went on, the temperature rose 3 degrees each hour.

Thus, the rate of change = slope = m = 3

Thus, substituting m = 3 and b = -7 in the equation

$y = mx+b$

$y = 3x + (-7)$

$y = 3x - 7$

Therefore, the equation shows the temperature over time will be:

$y = 3x - 7$

Hence, option (C) is correct.
