Answer:x = -0.1290322581
Step-by-step explanation:
Simplifying
9x + -4(1 + 10x) = 0
9x + (1 * -4 + 10x * -4) = 0
9x + (-4 + -40x) = 0
Reorder the terms:
-4 + 9x + -40x = 0
Combine like terms: 9x + -40x = -31x
-4 + -31x = 0
Solving
-4 + -31x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + -31x = 0 + 4
Combine like terms: -4 + 4 = 0
0 + -31x = 0 + 4
-31x = 0 + 4
Combine like terms: 0 + 4 = 4
-31x = 4
Divide each side by '-31'.
x = -0.1290322581

In the given equation, k is a constant. If the equation has no solution, what is the value of k?
Answers
Answer:
0
Step-by-step explanation:
The value of constant 'k' will be [tex]\frac{1}{3}[/tex].
Given equation in the question is,
[tex]\frac{1}{3}\times (x-k)=kx[/tex]
Further solve the expression for the solution of the equation.
[tex]\frac{3}{3}\times (x-k)=3kx[/tex]
[tex](x-k)=3kx[/tex]
[tex]x-3kx-k=3kx-3kx[/tex]
[tex]x-3kx-k=0[/tex]
[tex]x(1-3k)=k[/tex]
[tex]\frac{x(1-3k)}{(1-3k)}=\frac{3kx}{1-3k}[/tex]
[tex]x=\frac{3kx}{(1-3k)}[/tex]
Since, equation has no value, denominator will be zero.
[tex]1-3k=0[/tex]
[tex]1=3k[/tex]
[tex]k=\frac{1}{3}[/tex]
Therefore, Option (D) will be the correct option.

3/x-4 = x-5/x
Answers
The solution of the given equation are; X = -2 - 2√3 or x = -2 + 2 √3
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
We have been given an equation as 3/x-4 = x-5/x
Therefore, 3/x-4 = x-5/x
3 - 4x /x = x² - 5 / x
Cancel out the denominator;
3 - 4x = x² - 5
x² - 5 - 3 + 4x = 0
x² - 8 + 4x = 0
x² + 4x - 8 = 0
For the value of x;
x = 4 + √16 + 32 / 2
x = -2 + 2√3
OR
x = 4 - √16 + 32 / 2
x = -2 - 2√3
Hence, The solution of the given equation are; X = -2 - 2√3 or x = -2 + 2 √3

5. What is the next term of the sequence -3, 6, -12, 24,... , and what it's arithmetic sequence?
Answers
Answer:
a(5)=-48
Step-by-step explanation:
I think u r confused
this sequence is geometric not arithmetic
HOw we know that ??
when we get a common difference that must Be equal
d=6+3=9 not equal to d=-12-6=-18
So it is not arithmetic
but when we get the common ratio that also must be equal
r=6/-3=-12/6=24/-12=-2 equal
So it is geometric
By using this equation:
a(n)=a*r^(n-1)
and we have a=-3 , r=-2
Then a(n)=-3*(-2)^(n-1)
To get the next term:
a(5)=-3*(-2)^(5-1)
a(5)=-3*(-2)^(4)
a(5)=-3*16=-48

But the function of represent the points earned as a function of the total amount spent ask. Write a function that represents the total number of points earned us as a function of the amount spent
Answers
Answer:
F(p) = 500 + 0.5p
Step-by-step explanation:
Given that :
Bonus point on first purchase = 500
Number of points earned for every 2 dollar spent = 1
Points earned as a function of amount spent :
Bonus point + points earned per dollar
Number of points earned per dollar = 1 / 2
Let p = amount spent
F(p) = function representing the points earned
Hence,
F(p) = 500 + 0.5p

The Rodriguez family's ate 1/3 of a pan of brownies, they will take One part to their block party and the other to share with the co-workers. How much of the whole pan of brownies will each plate get?
Answers
Answer:
[tex]\dfrac{1}3[/tex]
Step-by-step explanation:
Given that:
Part of pan of brownies eaten by Rodriguez family = [tex]\frac{1}{3}[/tex]
One part of the remaining pan of brownies will be taken to the block party.
And the other part of the remaining pan of brownies will be given to the co-workers.
To find:
How much of the whole pan of brownies will be in each plate?
Solution:
First of all, let us find the remaining part of brownies after the family ate [tex]\frac{1}{3}[/tex] part of the pan.
Remaining = [tex]1-\frac{1}{3}=\frac{2}{3}[/tex]
Now, from the remaining pan of brownies, they are divided in 2 halves.
These part will be equal to:
[tex]\dfrac{\frac{2}{3}}{2} = \bold{\dfrac{1}{3}}[/tex]
Therefore, the answer is:
[tex]\dfrac{1}3[/tex]
