45 - 2t < 32 ( where t is time and you can replace it with x or h if you prefer)
Solving for t you get:
45 - 2t - 32 < 0
45 - 32 < 2t
13 < 2t
13/2 < t
Or the temperature will drop below 32F after 6 and a half hours

Answer:

If 23-26, that is -3

Well, because 23 can't minus 26, that's why you have to rearrange so that you can find the correct answer by letting -26 + 23.

Kelly is 3 years younger than her sister. The sum of their ages is 34 years. How old is Kelly and how old is her sister? AN EQUA
KiRa [710]
Kelly's sister is x years old.
Kelly is 3 years younger than her sister, so Kelly is x - 3 years old.
The sum of their ages is x + x - 3 = 2x - 3.
The sum of their ages is 34, so

2x - 3 = 34

2x = 37

x = 18.5 Kelly's sister's age.

x - 3 = 18.5 - 3 = 15.5 Kelly's age.

Kelly's sister is 18.5 years old.
Kelly is 15.5 years old.

The graph of a linear function is shown<br> below. What is the domain of the<br> function?
Viktor [21]

Answer:

{ x | -3 <= x < +1 }

Step-by-step explanation:

We note that the graph occupies from x=-3 to x=+1, while -3 is a value included (endpoint is solid), and +1 is excluded (endpoint hollow).

Thus the domain is { x | -3 <= x < +1 }
