Answer: 3
Step-by-step explanation: When you solve for x you get 2 so when you put that into the equation (2+1) you get 3. You solve for x but solving this equation (x+5) = (x+1) Hope this helps :)
In both cases, we have cooling. We can add together the 2 functions describing this cooling: z(x) = 0.5x - 9 - [-x-2] = 0.5x - 9 + x + 2, or
z(x) = 1.5x - 7
Provided that this is correct, all we have to do now is to subst. 5 for x:
z(5) = 1.5(5) - 7 = 7.5 - 7 = 0.5 (answer)
Answer:
Yes; 2/3
Step-by-step explanation:
The rate of change is 2/3 because from the first dot to the next, it moves up two and to the right 3. This is a linear relationship because the rate of change is constant, meaning it never changes.
Answer:
C) 16.50

Edit: Thank you for brainliest!
Good luck with your homework :>

Sorry if I explain things badly or give you the wrong answer
-12-0/4-0 = -12/4 = -3
0= -3(0) + b
B= 0
Y= -3x
Hope this helps!
