A value will be excluded from a rational expression if it causes the denominator to be zero as dividing by zero is undefined.
An example that would work for your specific question is:
If you plug in either 2 or 5 into this equation the denominator will be zero causing the expression to undefined there, so the values 2 and 5 are excluded from the domain of the expression.
Amanda must spend more than 8 minutes on Routine #1 to burn more calories than Routine #2.
Step-by-step explanation:
Routine # 1;
Calories burned in running = 15.5 per minute
Let,
t be the minutes spent running.
T = total calories burned
T = 15.5t
Routine # 2;
Calories burned while walking = 22 calories
Calories burned while running = 12.75 per minute
T = 12.75t + 22
For burning more calories in Routine 1;
Routine 1 > Routine 2
Dividing both sides by 2.75
Amanda must spend more than 8 minutes on Routine #1 to burn more calories than Routine #2.

Answer:
I think its 21.6 or 22 (Mostly 21.6 though) Sorry if its not right but i'm mostly sure of it like this!
Step-by-step explanation:
0 = 4 - 7 x^2 + x
0= (-7)x^2 + (1)x + 4
a= -7
b = 1
c= 4
Answer:
A. h = 4
B. g = 15
C. b = -6
D. b = 15
Step-by-step explanation:
A. 9h + 8 - 12 = -40
9h - 4 = -40
+ 4 + 4
9h = -36
h = -4
B. 9 + 6g + 1 = 100
10 + 6g = 100
- 10 - 10
6g = 90
g = 15
C. -45 = 28 - 13 + 10b
-45 = 15 + 10b
- 15 - 15
-60 = 10b
b = -6
D. 37 = 11 +3b - 19
37 = 3b - 8
+ 8 + 8
45 = 3b
15 = b
