Can the polynomial in the numerator of the expression x^2-5x+7/x-9 be factored to derive (x − 9) as a factor
Answer:
Step-by-step explanation:
We can find out by using synthetic division and the fact that x - 9 Might be a 0. If x = 9 is a 0 of that polynomial, then we will get no remainder when we divide the polynomial by 9:
9 | 1 -5 7
____________
First thing to do is bring down the 1 and multiply it by the 9 and put that product up under the -5:
9 | 1 -5 7
______9____
1
Now add down the column to get:
9 | 1 -5 7
_____9____
1 4
Now multiply 4 by 9 and put that product up under the 7:
9 | 1 -5 7
______9__36
1 4
Now add to see what the remainder is:
9 | 1 -5 7
_______9_36
1 4 R43
we have a remainder of 43. Since it is not a 0, then the polynomial is not evenly divisible by x - 9.
So the answer is No.

A certain pet store sells 6 times as many fish as kittens. It sells twice as many kittens as lizards. If the pet store sells 15 lizards a week, how many fish, kittens, and lizards does the pet store sell every week?
It sells twice as many kitten as lizards:
Kittens sold = 15 x 2 = 30 total kittens.
It sells 6 times the amount of fish:
Fish sold = 6 x 30 = 180 total fish.
Lizards = 15
Kittens = 30
Fish = 180
Answer:
They sell 225 pets each week.
Step-by-step explanation:
Let f be fish, k be kittens, and l be lizards.
[tex]f[/tex]÷6=[tex]k[/tex]
[tex]k[/tex]÷2=[tex]l[/tex]
If [tex]l=15[/tex], then:
[tex]k=30\\f=180[/tex]
180+30+15=225 pets
They sell 225 pets each week.

Answer:
? = 2 sqrt(21)
Step-by-step explanation:
We can use the Pythagorean theorem to solve since this is a right triangle
a^2 + b^2 =c^2
?^2 + 4^2 = 10 ^2
?^2 + 16 = 100
Subtract 16 from each side
?^2 +16-16 = 100-16
?^2 = 84
Take the square root of each side
sqrt(?^2) = sqrt(84)
? = sqrt(4) sqrt(21)
? = 2 sqrt(21)
Answer:
[tex]? =9.16515139[/tex]
Step-by-step explanation:
→You can use the Pythagorean Theorem:
[tex]a^2+b^2=c^2[/tex]
→The "a," and "b," are the legs, and the "c," is the hypotenuse. In this case, we area already given the hypotenuse (10), and are solving for the leg. So plug in the numbers, like so:
[tex]4^2+b^2=10^2[/tex]
[tex]16 + b^2=100[/tex]
→Subtract 16 from both sides:
[tex]b^2 = 84[/tex]
→To get "b," by itself, square root both sides, like so:
[tex]\sqrt{b^2} = \sqrt{84}[/tex]
[tex]b = 9.16515139[/tex]
Please help with these questions :(
In the Pythagorean theorem, a squared minim b squared equals c squared. If you apply that formule to question 2.
17^2-8^2 = 289 - 64 = 225 = 15^2.
Therefore, the answer to first question is yes
Then, for question 2, you do the same thing.

The list price of an item is $ 93.45. The supplier is offering a series trade discount of 7/23. Find the net cost.
Answer: $66.92
Step-by-step explanation:
We can get the final price by calculating the first discount and then subtracting this from the original price to get the amount to which the second discount is applied. We can then determine the final price by subtracting the second discount from the intermediate price.The percent of the first discount is 7.
The price after the first discount is $93.45−($93.45×0.07)=$86.91.
The price to which the second discount is applied is $86.91.
The second discount is 23%
86.91 x 0.23 = $19.99
The final price is (86.91 - 19.99) = 66.92
You deposit $1000 in an account that pays 4 1/2% annual interest compounded monthly. How much will you have in the bank after 9 years
Answer:
1498.17
Step-by-step explanation:
formula A = P[tex](1 + \frac{r}{100} )^{n}[/tex] where r is the rate of interest compounded and n is the number of times compounded.
r = 4.5 / 12 = 0.375 since it is compounded monthly thus need to divide by 12 months
n = 9 x 12 = 108 ( 9 years in months)
A = 1000[tex](1 + \frac{0.375}{100})^{108}[/tex] = 1498.167
Answer:
Step-by-step explanation:
A = I(1+r/n)^nt
A = ?
I = $1000
r = 4.5% = 4.5/100 = 0.045
n = 12
t = 9
A = 1000(1+0.045/12)^108
A = 1000(1.00375)^108
A = $1498.17
Which function is the inverse of f Superscript negative 1 Baseline (x) = negative one-fifth x minus four-fifths? f Superscript negative 1 Baseline (x) = negative one-fifth x + four-fifths
Answer:
The inverse of the function is [tex]g (x)=-5x-4[/tex].
Step-by-step explanation:
The function provided is:
[tex]f^{-1}(x)=-\frac{1}{5}\ x-\frac{4}{5}[/tex]
Let us assume that:
[tex]y=f^{-1}(x)[/tex]
Then the equation will be:
[tex]y=\frac{-x-4}{5}[/tex]
To compute the inverse of the function substitute x as y and y as x.
[tex]x=\frac{-y-4}{5}[/tex]
Now solve for y as follows:
[tex]x=\frac{-y-4}{5}[/tex]
[tex]5x=-y-4[/tex]
[tex]y=-5x-4[/tex]
Thus, the inverse of the function is [tex]g (x)=-5x-4[/tex].
Answer:
The answer is "-5x-4"
Step-by-step explanation:
Given:
[tex]\bold{f^{-1} (x)=(-\frac{1x}{5}-\frac{4}{5})}[/tex]
solve the above equation:
[tex]\to f^{-1}(x)= \frac{-x-4}{5}\\\\\to f^{-1}(x)= -\frac{x+4}{5}\\[/tex]
Let
[tex]y= f^{-1} x= -(\frac{x+4}{5})\\\\[/tex]
inverse the above function:
[tex]\to x= -(\frac{y+4}{5})\\\\\to 5x= -(y+4)\\\\\to 5x= -y-4\\\\\to\boxed {y=-5x-4}\\\\[/tex]

8. Write the equation of the line in slope-intercept form that passes through (10.21) and (15.36)
Answer:
y = 3x - 9
Step-by-step explanation:
First, find the slope using y2 - y1 / x2 - x1
36 - 21 = 15
15 - 10 = 5
15/5 = 3, so the slope (m) is 3.
Now, plug into point-slope form: y - y1 = m (x - x1)
y - 21 = 3 (x - 10)
Simplify
y - 21 = 3x - 30
y = 3x - 9

Answer:
total cup = 32
1 student = 1/2 cup
find remaining cup = y
*we don't know how many students are there, so we just let it be x .
remaining cup = total cup - cup drank by students
y = 32 - 1/2x
y = -1/2x + 32 ( option c )
why 1/2x ? because we don't know how many students drank the juice, so we just let it be x .

What is the simplified form of the expression?
(3x^2+5x-8)+(5x^2-13x-5)
= 3x^2 + 5x^2 = 8x^2
5x - 13x = -8x
-8 + -5 = -13
=> 8x^2 - 8x - 13
: B
Answer:
8x2 − 8x − 13
Step-by-step explanation:
(((3•(x2))+5x)-8)+((5x2-13x)-5)
((3x2 + 5x) - 8) + (5x2 - 13x - 5)
Factoring 8x2-8x-13
The first term is, 8x2 its coefficient is 8 .
The middle term is, -8x its coefficient is -8 .
The last term, "the constant", is -13
Step-1 : Multiply the coefficient of the first term by the constant 8 • -13 = -104
Step-2 : Find two factors of -104 whose sum equals the coefficient of the middle term, which is -8 .
-104 + 1 = -103
-52 + 2 = -50
-26 + 4 = -22
-13 + 8 = -5
-8 + 13 = 5
-4 + 26 = 22
-2 + 52 = 50
-1 + 104 = 103
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
8x2 - 8x - 13 ✅

If the first three Fibonacci numbers are x1 = 1, x2 = 1, x3 = 2, what is the value of n for which xn + xn+1 + xn+2= 68?
Answer:
13, 21, and 34
Step-by-step explanation:
x(n) + x(n+1) + x(n+2)= 68
x(n), x(n+1), and x(n+2) are three consecutive Fibonacci numbers.
=> (x) + (x+k) + (x+x+k)=68
(x is a Fibonacci number and k is a positive integer)
=> 4x + 2k = 68
=> 2x + k = 34
=> x < 17
Check two Fibonacci numbers that are closest to 17 and smaller than 17.
x(n)=8 => x(n+1)=13, x(n+2)= 21
=>x(n) + x(n+1) + x(n+2)= 8 + 13 + 21 = 42 (not valid)
x(n) = 13 => x(n+1) = 21, x(n+2)= 34
=> x(n) + x(n+1) + x(n+2)= 13 + 21 + 34 = 68 (valid)
Hope this helps!
