Answer:
A
Step-by-step explanation:
[tex]f(x)=\dfrac{x^2-36}{x+6}= \\\\\\\dfrac{(x-6)(x+6)}{x+6}= \\\\\\(x-6) \\\\\\f(-6)=((-6)-6)=-12[/tex]
Therefore, the correct answer is choice A. Hope this helps!
Answer:
=-12
Step-by-step explanation:
f(x) = (x^2-36)/(x+6)
Factor the numerator. The numerator is the difference of squares
(a^2 -b^2) = (a-b)(a+b)
f(x) = (x-6)(x+6)/(x+6)
Cancel the like terms
f(x) = x-6
f(-6) = -6-6
= -12
Given f(x) = –2x + 2, find f(6).
Answer:
-10
Step-by-step explanation:
_________________________________
Solution,
f(X)= -2x+2
f(6)= -2*6+2
= -12+2
= -10
So the right answer is -10.
hope it helps
Good luck on your assignment

If you had a nickel (.05 or five cents) that earned 100 percent interest each day or doubled in value each day. How much would you have after 10 days?
Answer:
Step-by-step explanation:
If the initial amount of nickel is doubling in value each day, it means that the amount of nickel is increasing in geometric progression. The formula for determining the nth term of a geometric sequence is expressed as
Tn = ar^(n - 1)
Where
n represents the common ratio
a represents the first term of the sequence (initial amount)
n represents number of terms in the sequence (days)
r represents common ratio between consecutive terms(days)
From the information given,
r = 2
n = 10
a = 0.05
Therefore, for 10days, T10
T10 = 0.05 × 2^(10 - 1)
T10 = 0.05 × 2^9
T10 = 25.6
Answer:
Having a nickel doubled for 10 days gives 512 nickels, or 2560 cents.
Step-by-step explanation:
Having a nickel doubled in value each day for 10 days, we first write the amount of nickels we have in the first few days, inspect what pattern these numbers take, write a general formula for the sequence formed, and use the formula to find the 10th number easily.
For the first five days we have:
Day1: 1
Day2: 1 + 1 = 2
Day 3: 2 + 2 = 4
Day 4: 4 + 4 = 8
Day 5: = 8 + 8 = 16
...
This is a geometric progression, where the first term is 1, and the common ratio is 2.
The nth term is given as
Tn = ar^(n - 1)
Tn = 1 × 2^(n - 1)
= 2^(n - 1)
That is
Day n = 2^(n - 1)
Day 10 = 2^(10 - 1) = 2^9 = 512 nickels.
But because 1 nickels = 5 cents
512 nickels = 5 × 512 = 2560 cents.

What's the distance between - 14 and -5 on a number line?
A) 34
B) 11.7
D) 68
Question 15 (5 points)
Answer:
9
Step-by-step explanation:
Take -14 minus -5
-14 - (-5) Distribute the negative to -5
-14 + 5 Add
-9 Since distance can't be negative take the absolute value of -9
|-9| = 9
Answer:
the distance is 9
Step-by-step explanation:
its 9 because 14-5 = the distance of them on a number line

Determine which sequence is an arithmetic sequence.
Question 18 options:
a)
–7, –3, 1, 5, ...
b)
15, 17,19, 111, ...
c)
−10, 5, −52, 54, ...
d)
3, 6, 12, 24, ...
Answer: A
Step-by-step explanation: An arithmetic sequence is a pattern in which the same number is repeatedly added or subtracted.
Notice that in the the first sequence shown, we add 4 to reach the next term in the sequence which means this is arithmetic.
The others are not arithmetic because the difference
between the terms does not remain constant.

Find the value of x that makes line m parallel to line
n.
(4x - 23)
n
{
(2x + 17)
Answer:
20
Step-by-step explanation:
If lines m and n are parallel, then the labelled angles would be considered alternate exterior angles. By definition, such angles are of the same value.
Thus, we set the two expressions of 4x - 23 and 2x + 17 equal:
4x - 23 = 2x + 17
Subtract 2x from both sides and add 23 to both sides:
2x = 23 + 17 = 40
Divide by 2:
x = 40/2 = 20
The answer is thus 20.
~ an aesthetics lover
Answer:
[tex]x=20[/tex]
Step-by-step explanation:
Alternate exterior angles are a pair of equal angles on opposite sides of the transversal.
[tex]4x-23=2x+17[/tex]
[tex]4x-23+23=2x+17+23[/tex]
[tex]4x=2x+40[/tex]
[tex]4x-2x=2x+40-2x[/tex]
[tex]2x=40[/tex]
[tex]\frac{2x}{2}=\frac{40}{2}[/tex]
[tex]x=20[/tex]

Answer:
6. The relationship is they multiply the first box of glasses by the amount of boxes 15glasses = x 3,
30 glasses = x6
45 glasses = x 9
60 glasses = x 12
75 glasses = x15
= 30, 45, 60,75
But in between glass amount 45 +60 they show a midpoint amount of glasses in a box where 45 = 9n then 55 = 11n and stands out as 11 boxes as an offset amount of glasses where 5 are in each box.
7. Robert is incorrect as 25 x 5 = 125 and not 120
as 120 and 125 glasses can be divided to check
125/25 = 5 and could be correct if he wanted spare glasses = 1 spare box.
But when we check 120/25 = 4.8 so this would be too many boxes as he would only need 24 boxes.
24 x 5 = 120 glasses.
