9-(2/x)
Step-by-step explanation:
This represents the expression.
If f(x) = x3 - 12x2 + 44x - 48, which of the following is not a factor of f(x)? O (x + 4) O (x - 6) O (x - 2) O (x - 4)
Answer:
(x + 4)
Step-by-step explanation:
x - 2 = 0, so x = 2
x - 4 = 0, so x = 4
x - 6 = 0, so x = 6
The option which is not a factor of the cubic equation is (x+4)
What are cubic equations?The algebraic equations having variables with power 3 are referred to as cubic equations. A generalized form of a cubic equation is ax³+ bx²+ cx + d = 0.
Given here: The cubic function f(x)=x³-12x²+44x-48
Clearly in the options the list of factors are -4,6,2,4
Checking for all 4 options we get
f(-4)=-4³-12×4²+44×(-4)-48
=-64-192-176-48≠0
f(6)=6³-12×6²+44×(6)-48
=216-12×36+264-48
=0
f(2)=2³-12×4+44×2-48
=8-48+88-48
=0
Similarly we can find for x=4 that f(4)=0
Hence, The option which is not a factor of the cubic equation is (x+4)

On selling 250 cascades, a man had an equal gain to the selling price of 25 cascades. Find his gain percent
Answer:
11.11%
Step-by-step explanation:
The selling price is 250
The cost price is 250-25
= 225
Therefore the gain can be calculated as follows
=250-225x/225x×100
1/9 ×100
= 0.1111×100
= 11.11%
Hence the gain is 11.11%

I need help math work (geometry) :P
Answer:
x = 6
Step-by-step explanation:
For the triangles to be similar then the ratios of corresponding sides would be equal, that is
[tex]\frac{DF}{XZ}[/tex] = [tex]\frac{DE}{XY}[/tex] , substitute values
[tex]\frac{3(x-1)}{7.5}[/tex] = [tex]\frac{10}{x-1}[/tex] ( cross- multiply )
3(x - 1)² = 75 ( divide both sides by 3 )
(x - 1)² = 25 ( take the square root of both sides )
x - 1 = ± [tex]\sqrt{25}[/tex] = ± 5 ( add 1 to both sides )
x = 1 ± 5 , then
x = 1 + 5 = 6 or x = 1 - 5 = - 4
But x > 0 then x = 6
For the triangle to be similar then x = 6

Find Ms. Buggie's mistake in the following problem. Then, give what the correct answer should be.
Find the measurement of angle LKA.
Answer:
Mrs. Buggie should have Subtracted 13 instead of adding 13
LKA = 94°
Step-by-step explanation:
Lets work backwards from the equation so far:
40 = x+ 13
x + 13 = 40
We should subtract 13 because we are adding a number and 13 to 40
Imagine this:
You have 5 apples, but you bought some more and now you have 10
equation would be:
5+x = 10
subtract 5 from 10 to get 5
So you bought 5 apples
Back to the Question:
40 - 13 = 27
3(27) + 13 = 81+13 = 94°
Answer = 94°

i would offer more points but i dont have anymore
Answer:
1.) x=-7
2.) x= -8
3.) x=13
4.) x=2
Step-by-step explanation:
ur lucky idc
1. 4x = -28
By dividing both sides of this equation by 4, we see that x = -7.
2. x - (-6) = -2
Note that x - (-6) is equal to x + 6. To solve the equation x + 6 = -2, subtract 6 from both sides to see that x = -8.
3. -x + 4 = -9
First, subtract 4 from both sides to get that -x = -13. Then, multiply both sides by -1 to see that x = 13.
4. -3x + 7 = 1
First, subtract 7 from both sides to get that -3x = -6. Then, divide both sides by -3 to see that x = 2.

If 1/8 of my money is $80. What is 50 % of my money
Answer:
$320
Step-by-step explanation:
An easy way to solve this problem is to undo the operations, Find the total amount of money, and then find half of the amount. Since (80) is ([tex]\frac{1}{8}[/tex]) the total amount of money, one has to multiply (80) by (8) to find the total amount of money.
(80) * (8)
= 640
Now one is asked to find (50%) of the money. It is known that (50%) is equivalent to (0.5), therefore multiply (640) by (0.5) to find how much (50%) of the money is.
(640) * (0.5)
= 320
