Answer:
x=

≈1.866025404
Step-by-step explanation:
Answer:
If x^3+1\x^3=18, then what is the value of x?
x^3 +1/x^3= 18.
Formula:-
(x +1/x)^3 = x^3. +1/x^3 + 3.(x +1/x).
Let (x+1/x)= p.
or, p^3 =18 +3p.
or, p^3 -3.p -18 =0.
Putting p=3 , remainder = 3^3–9–18 = 0 , (p-3) is a factor.
or, p^2.(p-3)+3.p^2-3p-18=0
or, p^2.(p-3)+3.p.(p-3)+6.(p-3)=0.
or, (p-3).(p^2+3p+6)=0
Either p-3=0.
or, p = 3. , putting p = x +1/x.
or, x +1/x = 3. ……………….(1).
And, (x -1/x)^2 = (x+1/x)^2 - 4. = 3^2 - 4 = 5.
Thus, x -1/x = +/-√5. …………….(2).
Adding eqn.(1) and (2).
2.x = 3+/-√5.
or, x = (3+/-√5)/2. Answer.

Step-by-step explanation:
Your fitness tracker overestimates the number of steps you take by 5%. The trackers indicates that you took 7350 steps today. Write and solve an equation to find the actual number of steps you took today.
The equation (1 + 0.05)x = 7350 to find the actual number of steps you took today will be 7,000.
What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.
Your fitness tracker overestimates the number of steps you take by 5%. The trackers indicate that you took 7350 steps today.
Let x be the actual number of steps. Then the equation will be given as,
(1 + 0.05)x = 7350
x = 7350 / 1.05
x = 7,000
The actual number of steps you took today will be
(1 + 0.05)x = 7350
x = 7350 / 1.05
x = 7,000
The equation (1 + 0.05)x = 7350 to find the actual number of steps you took today will be 7,000.

Which equation can be used to calculate the area of the shaded triangle in the figure below?
A) 2(12 + 4) = 32
B) fraction 1 over 2 (12 + 4) = 8
C) 2(12 × 4) = 96
D) fraction 1 over 2 (12 × 4) = 24
Answer:
D) 1/2 (12x4)=24
Step-by-step explanation:
The answer is D because 12 times 4 gets you the area of the whole rectangle, but then you multiply it by 1/2 to get half of the rectangle's area, which is the shaded part.
please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.
thank you!
The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

You have a pizza with diameter 12

3 as a decimal. Can you fit the pizza inside the box?
What is the decimal expansion for 12
2
3?
A.12.6
B.12.65
C.12.6
D.12.66
pls help me
Answer:
D is the right choice and no you cannot fit the pizza inside the box.
Step-by-step explanation:
D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.
Answer:
I believe the answer is D.

27. Solve the equation.
Answer: r=-56
Step-by-step explanation:
multiply 7 on both sides
\(\frac{7r}{7}=7\left(-8\right)\)
7*-8=-56
7 and 7 is eliminated
so x=-56
Answer:
r= -56
Step-by-step explanation:
The equation given is:
\(\frac{r}{7}= -8\)
We want to solve for r. In order to do this, we must get r by itself.
Currently, r is being divided by 7. We want to perform the inverse, which is multiplication. Therefore, we should multiply both sides of the equation by 7.
\(7*\frac{r}{7}= -8 * 7\)
\(r=-8*7\)
\(r= -56\)
Let's check our solution. Substitute -56 back in for r and solve.
\(\frac{r}{7}= -8\)
\(\frac{-56}{7}= -8\)
\(-8=-8\)
Both sides of the equation are the same, so we know our answer is correct.

James buys 4 pens for $3. Which three points lie on the line that best represents the total cost, y, of x pens?
Which order pair is NOT on the line that best represents this relationship?
Responses (8,6) (4,3) (0,0) (6,8)
James buys 4 pens for $3, so each pen costs $3/4. The total cost of x pens is $3x/4.
The points (0,0), (4,3), and (8,6) all lie on the line y = $3x/4. The point (6,8) does not lie on this line.
Therefore, the answer is (6,8).
