216 3
1296 4
7776 5
Answer:
Step-by-step explanation:
216 =6^3
1,296 = 6^4
7,776 = 6^5
x = 6^f(x)
log x = log 6^f(x) = f(x)log 6
f(x) = log x / log 6 =

Answer:
Rate of change is correct; it's -3. And when the x-value is 8, the y-value is just a value, not a coordinate point. It's one number. -3 would not be the answer, and i dont know what the answer would be, but it's between greater than -14 and less than -23. Hope this helps!!

For the polynomial
f(x) = 2x4 – 8v? + 77-25
as
X->
→ -*f(x) –
- DO
We can conclude that as x tends to negative infinity, f(x) will tend to positive infinity is a TRUE statement.
Given the polynomial function expressed as:
[tex]f(x)=2x^4-8x^2+7x-25[/tex]
If x tends to negative infinity, the polynomial function will become:
[tex]f(x)=2(-\infty)^4-8(-\infty)^2+7(- \infty)-25\\f(x)=2(\infty)-8(\infty)+7(- \infty)-25\\f(x)=\infty -\infty -7\infty - 25\\f(x) =\infty - 25[/tex]
Since infinity is a large number, therefore subtracting 25 from it will not have any effect on it and will still return a positive infinity.
Hence we can conclude that as x tends to negative infinity, f(x) will tend to positive infinity is a TRUE statement.

Answer:
(-2, 2) (-4, 2) (-4, 5)
Step-by-step explanation:
The coordinate for A are (2, 2) (4, 2) and (4, 5).
When you reflect across the x=axis the y coordinates become negative.
(2, -2) (4, -2) (4, -5)
y = x is a diagonal line through the origin, and all of the points change signs.

At your school, the building is 20 feet tall, a tree's height is 252 inches, and the flagpole is 6 yards high.
Which of the three objects casts the longest shadow?
Answer: The Tree height is 21 feet.
Step-by-step explanation:
Let's convert the measurements to feet:
The Building is 20 feet.
The Tree height is 21 feet.
The Flagpole is 18 feet.
Therefore, the Tree is going to cast the longest shadow since it is the highest.

Determine whether the ratios form a proportion.
16/9, 28/15
Answer:
No
Step-by-step explanation:
One way of doing this problem is to reduce the given fractions as much as possible. Unfortunately, neither ratio reduces. So the fraction 16/9 is NOT equal to the fraction 28/15 and our conclusion must therefore be "the rations do not form a proportion."

has 11 more friends than Xander when they start the competition. After much work, Kennedy doubles her amount
of friends and Xander quadruples (4 times) his. In the end they have a total of 232 friends.
Answer:
Xander has 140 friends
Kennedy has 92 friends
Step-by-step explanation:
Let x represent # of friends Xander has at the start
Let x+11 represent # of friends Kennedy has at the start
Let 2(x+11) rep. the final # of friends Kennedy has
Let 4x rep. the final # of friends Xander has
Total = 232
So we just need to solve for x:
2(x+11) + 4x = 232
2x + 22 + 4x = 232
6x = 210
x = 35 < - This means that xander started with 4 friends.
Sub x to find friends for each:
4x = ?
4(35) = 140 friends
2(x+11) = ?
2(35+11) = 92

what is the domain of f? khan academy
Answer:
x cannot = -2
Step-by-step explanation:
if x = -2 then the denominator is 0 and a fraction with 0 as a denominator is undefined.
Answer:
A
Step-by-step explanation:
f(x) = [tex]\frac{x-3}{x+2}[/tex]
The denominator cannot be zero as this would make f(x) undefined.
Equating the denominator to zero and solving gives the value that x cannot be.
x + 2 = 0 ⇒ x = - 2 ← excluded value in the domain
The domain of f(x) is all real values of x such that x ≠ - 2

Mrs. Adenan sold 63 bracelets at one craft fair and 36 bracelets at a second craft fair. Which expression correctly applies the distributive property to show equivalent expressions for the total number of bracelets she sold?
63 + 36 = (3) (21) + (9) (4)
63 + 36 = (7) (9) + (12) (3)
63 + 36 = 9 (7 + 4)
63 + 36 = 3 (21 + 9)

If something cost $37.80, how many tens would you give?
Answer:
4 tens
Step-by-step explanation:
3 tens would get you $30, which is $7.80 short. If you give 4 tens you are giving $40 which is 2.20 more than $37.80, which is okay as you can probably get change and it is the least amount of tens you can give to cover the cost.
Mr. Capp runs his own disc golf store every Saturday. The first customer of the day came in and bought
1 driver and 2 putters for $43. The second customer came in and bought 3 drivers and 1 putter for $69.
How much money does one driver and one putter cost at Mr. C's store?
Answer:
a driver costs $19, while a putter costs $12
Step-by-step explanation:
driver = d
putter = p
1d + 2p = 43
3d + 1p = 69
d + 2p = 43. eq 1
3d + p = 69. eq 2
make d the subject of the equation
d = 43 - 2p. eq 3
substitute the value of d in eq 3 in eq 2
3(43 - 2p) + p = 69
129 - 6p + p = 69
collect like terms
129 - 69 = 6p - p
60 = 5p
p = 12
substitute the value of p in eq 3
d = 43 - 2(12)
d = 43 - 24
d = 19
