Answer:
{-5, -2}
Step-by-step explanation:
In a case like this please use parentheses to remove ambiguities. If I were to take your "x+5/x+2" literally, I'd have to write x plus 5/x plus 2.
I suspect that you actually meant (x + 5) / (x + 2), and will start with that.
First of all, this function is not defined at x = -5 or at x = -2. Thus, -5 and -2 are critical points.
Secondly, there may be one or more critical points beyond this. To find out, we have to differentiate (x+5)/(x+2):
(x + 2)(1) - (x + 5)(1)
f '(x) = ------------------------------
(x + 2)
Here it's clear that x cannot = -2, which would cause division by zero.
Thus, our critical values are {-5, -2}.
Answer:
413/45
Step-by-step explanation:
5 1/9=46/9
4 1/3=13/3
8 2/5=42/5
-----------------
46/9-13/3+42/5
46/9-39/9=7/9
7/9+42/5=35/45+378/45=413/45
Answer:
A. 4
Step-by-step explanation:
Negative negative 4 would be positive 4. The reason why is because if you multiplied -4 by -1, you'd get positive 4.
Answer:
Step-by-step explanation:
Answer:
x -intercept (31,0)
y-intercept (0,-31/10)
Step-by-step explanation:
x-10y=31
x-10(0)=31
x=31
x-10y=31
0-10y=31
-10y=31
y=-31/10
