10 !algebra 1 math the graph shows the temperature over a period of time of a chemical compound that is placed in a cold chamber. what is the domain of this function? graph showing a line segment that goes from ordered pairs 0, 20 to 35, negative 10 a. the domain is all real numbers 20 through negative 10. b. the domain is all integers from 20 through negative 10. c. the domain is all real numbers 0 through 35. d. the domain is all integers from 0 through 35.

Answer

It's not B: I got it wrong xD

Step-by-step explanation:

The correct option is C.

Step-by-step explanation:

It is given that a line graph shows the temperature over a period of time of a chemical compound that is placed in a cold chamber.

Domain is the set of all possible inputs for which function is defined.

If a function defined from to , then the domain is

The end points of the line are (0,20) and (35,10). It means lines segment joining these two points. The domain of the function is

It means domain of the function is all real numbers 0 through 35. Option C is correct.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
