Identify The domain of the rational function, g(x)= 1/x+3
A (-∞, ∞)
B (-∞, 3)U(3, ∞)
C (-∞, -3]U[-3, ∞)
D (-∞, -3)U(-3, ∞)
Answer:
The domain is (-∞ , -3) ∪ (-3, ∞) ⇒ D
Step-by-step explanation:
The domain of the rational fraction is the values of x which make the fraction defined. That means the domain does not contain the values of x which make the denominator equal to 0.
∵ g(x) = [tex]\frac{1}{x+3}[/tex]
∴ The denominator = x + 3
→ Equate the denominator by 0
∵ x + 3 = 0
→ Subtract 3 from both sides
∴ x + 3 - 3 = 0 - 3
∴ x = -3
→ That means the domain can not have -3 because it makes the denominator
equal to 0
∴ The domain is all values of real numbers except x = -3
∴ The domain = {x : x ∈ R, x ≠ -3}
∴ The domain = (-∞ , -3) ∪ (-3, ∞)

A) The mean decreases by 2 years.
B) The mean decreases by about I .6 years.
C) The mean increases by about 1.6 years.
D) The mean does not change.
Answer:
B
Step-by-step explanation:
Before you add 20 the mean is 37.1 after you add 20 it’s 35.54.
37.1-35.54=1.56
Round 1.56 to 1.6

Step-by-step explanation:
Answer:
33 deg
Step-by-step explanation:
Since <POQ is a right angle, lines MQ and PO are perpendicular. That makes <PON a right angle with measure 90 deg.
m<MOP + m<MON = m<PON
3x - 3 + 4x + 9 = 90
7x + 6 = 90
7x = 84
x = 12
m<MOP = 3x - 3 = 3(12) - 3 = 36 - 3 = 33
m<MOP = 33

121 cm
B.
11 cm
с
12 cm
D
13 cm
Answer:
B: 11
Step-by-step explanation:
121 is the area. Since a square is a shape with all even sides you need to find one number that multiplies by itself to get 121. 11x11=121
B: 11
Betty had 1/3 yard of ribbon. She used 1/2 of it. How many yards of ribbon did she use?
a. 6 yd
b. 1/6 yd
c. 2/3 yd
d 3/2 yd
Answer:
b. 1/6 yd
Step-by-step explanation:
When Betty used 1/2 OF the 1/3 yards she has she has to multiple those. It's easier to put it in a sentence in my opinion because then you can see the "of" in the sentence which means to multiply. Hope this helps!
