Lf x+1/x=12 then find the value of x3+1/x3​
Tresset [83]
Answer:

Explanation:

First we find what x is:
x + 1/x = 12
x + 1 = 12x
1 = 12x - x
1 = 11x
1/11 = x
Or x = 1/11

Plug x value in x^3 + 1/x^3

(1/11)^3 + 1/(1/11)^3
= (1^3/11^3)+ 1/(1^3/11^3)
= (1/1331 + 1)/1/1331
= (1/1331 + 1331/1331)/1/1331
= 1332/1331 x 1331/1
= 1332/1
= 1332

Therefore, x^3 + 1/x^3 = 1332

Parallel lines x and w are cut by transversals z and y and form 4 angles at each intersection. Where line x intersects with line
ale4655 [162]

Answer:

m\angle 1  =105^\circ\\m\angle 2  =75^\circ

Step-by-step explanation:

The diagram is drawn and attached below.

From the diagram

m\angle 2 =75^\circ $ (Alternate Angles)

m\angle 1+ m\angle 2 =180^\circ $ (Sum of angles on a straight line)\\m\angle 1+75^\circ  =180^\circ\\m\angle 1  =180^\circ-75^\circ\\m\angle 1  =105^\circ

PLEASE HELP On the number line, graph the solution to the inequality -5(x+1) > 7x + 31? Can you tell me how to go about doing
elena-s [515]

Answer:

I don't know how to insert a number line, but you have to put on it x<-3. You have to plot it, then put a open circle at -3, and draw an arrow, pointing it farther into the negitive side of the number line.

A line has a slope of 2/3 and a y-intercept of −5. Which equations represent the line? Choose all answers that are correct. (MUL
marin [14]
A.         -2x + 3y = -15
    -2x + 2x + 3y = 2x - 15
                     3y = 2x - 15
                      3          3
                       y = ²/₃ - 5
A is correct.

B. y = ²/₃ - 5
B is also correct.

C. 6y = 4x - 30
     6           6
       y = ²/₃x - 5
C is also correct.

D. y + 3 = ²/₃(x - 3)
     y + 3 = ²/₃(x) - ²/₃(3)
     y + 3 = ²/₃x - 2
         - 3          - 3
           y = ²/₃x - 5
D is also correct.

The answer to the problem is A, B, C, and D.
