Answer:
x = 7/4 = 1.75
Step-by-step explanation:
Hello - so you don't seem to have shown what the calculator screen displays, however I can assume it will show a graph of the two lines, and their intersection point. The x-co-ordinate of this intersection point is the solution to the equation.
As I can't see the calculator, I will also show you how to work out the solution for x:
3x - 1 = 6 -x
4x -1 = 6
4x = 7
x = 7/4 = 1.75
2400 miles in .........4 hours
X miles in .................1 hour
X = 2400 multiply 1 divided 4
X = 600 miles per one hour
Answer:
If the question comes from a textbook
Step-by-step explanation:
use slader
If it is perpendicular then the slope of it will be:
y = 1/3 x + b
-1 = (1/3)(3) + b
-1 = 1 + b
b = -2
The equation is:
Answer:
y = 2x(x - 21)
Step-by-step explanation:
The given quadratic function y = -40x + 2x^2 - 2x
This can be rearranged as
y = 2x^2 - 2x - 40x
Here the Greatest Common Factor is 2x, we can take it out and write the remaining term in parenthesis.
y = 2x(x - 1 -20)
y = 2x(x - 21)
That's the answer.
Hope this will helpful.
Thank you.
