Macaleh compared the prices of four different brands of coffee.

Which brand of coffee offers a proportional relationship between its weight and its price?

A. Brand 1
B. Brand 2
C. Brand 3
D. Brand 4

Brand 1

Step-by-step explanation:

4 Oz of coffee is 1.15

8 Oz of coffee is another 1.15 added, because it is another 4 Oz of coffee

12 Oz is another 1.15 added, it's another 4 Oz of coffee

And so on.

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
