Melissa and brian are at the base of a moutain. melissa hikes to a location 27 meters above sea. level brian hikes to a location 21 meters below sea level. write an integer to represent each hiker's location with respect to sea level.

Integer that represents Melissa's location with respect to sea level:

Integer that represents Brian's location with respect to sea level:

Step-by-step explanation:

By definition, Integers can be negative, positive or zero.

Let be zero () the sea level.

According to the information provided in the exercise, you know that Melissa's location is at 27 meters above the sea level.

Therefore, you can conclude that the integer that represents her location with respect to sea level, is greater than zero (this means that it is positive).

Then, this is:

Brian's location is 21 meters below sea level.

This indicates that the integer that represents her location with respect to sea level is less than zero (it is negative).

Therefore, this is:

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
