Answer: x=4
Step-by-step explanation:
-8-x=x-4x
-8-x=-3x
-x+3x=8
2x=8
x=4
Answer:
Here are two ways of writing it. I hope this helps!
Given:
Line of the graph
To find:
Equation of the line
Solution:
Take any two points on the graph of the line.
Let the points are (0, 3) and (3, 0).
Slope of the line:
Here,
m = -1
b = y-intercept
y-intercept of the graph is the point which x = 0.
y-intercept is 3 when x = 0.
⇒ b = 3
Equation of a line:
y = mx + b
y = -1(x) + 3
y = -x + 3
The equation of the line is y = -x + 3.

Answer:
27x^3 - 54x^2 + 36x - 8
Step-by-step explanation:
(3x - 2)^3
= (3x - 2) (3x - 2) (3x - 2)
= 27x^3 - 54x^2 + 36x - 8
