Answer:
Given, x−x1=5
Squaring both the sides,
⇒(x−x1)2=52
⇒x2+x21−2(x)(x1)=25
⇒x2+x21=25+2
⇒x2+x21=27
Now,
x3−x31
=(x−x1)[(x)2+(x1)2+(x)(x1)]
=5(27+1)
=140

Answer:
322
Step-by-step explanation:
Consider the cube ...
(a +b)³ = a³ +3a²b +3ab² +b³
= a³ +b³ +3ab(a+b)
Now, for a=x and b=1/x, we have ...
(x +1/x)³ = x³ +1/x³ +3(x)(1/x)(x +1/x)
Using the known value for x+1/x, this is ...
7³ = x³ +1/x³ +3(7)
x³ +1/x³ = 7³ -3·7 = 343 -21
x³ +1/x³ = 322

If you want to try this with numbers, the solutions to the original equation are ...
x ≈ 6.85410196625 and its reciprocal.
What is the result of solving this equation for x?
y−b=m(x−a)
Answer:
( y-b) / m +a = x
Step-by-step explanation:
y−b=m(x−a)
Divide each side by m
(y−b)m=m/m(x−a)
( y-b)/m = x-a
Add a to each side
( y-b) / m +a = x-a+a
( y-b) / m +a = x
Answer:
y − b = m(x − a)
y − b = mx - ma
(y - b) / m = x - a
((y-b)/m) + a = x

write an equation for a line perpendicular to y=5x+2 and passing through the point (-10,3)
Step-by-step explanation:
The perpendicular line *always* has a slope of the negative reciprocal. Your given line has a slope of -5, so the perpendicular slope is -1/(-5) = 1/5.
Use the point-slope form of a general line to find the equation.
(y - y_1) = m * (x - x_1)
y - 7 = (1/5) * (x - 15)
