T(p) is a function that models the average yearly temperature based on the degree latitude(p) of the location on earth. the lines of latitude run from east to west, but they are measured in terms of north and south, extending from −90° to +90°. which domain is appropriate for this function?

D = all real numbers between ± 90, inclusive

Step-by-step explanation:

Degrees of latitude can be fractional units, positive units, or negative units.

All the real numbers between including .

Step-by-step explanation:

T(p) models the average yearly temperature based on degree latitude of the location.

Since the lines of latitude runs from East to West and extending from to , they can be included in the domain.

Also, the degrees of latitude can be fractional units, positive units, or negative units. Therefore, the domain appropriate for this function is All the real numbers between including .

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
