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:
12
Step-by-step explanation:
First fraction:
Numerator:
(17/40 + 0.6 - 0.005) = 1.02
1⅕ = 1.2
(1.2 ÷ 1.02)×1.7 = 2
Denominator:
5/6 + 4/3 - 53/30
Lcm: 30
(5×5 + 4×10 - 53)/30
12/30 = 0.4
Fraction value: 2/0.4 = 5
Second fraction:
4.75 + 7.5 = 12.25
33 ÷ 33/7
33 × 7/33 = 7
12.25/7 = 1.75
1.75 ÷ 0.25 = 7
Final answer:
5 + 7 = 12
Answer:
O.26
Step-by-step explanation:
Divide The cost from the pieces
#1: 4*5 + 4*6=20+24=44
#2: 4*(5+6)=4*11=44
