5x – 1 = 3x – 15
Subtraction Property of Equality (Subtract 3x from both sides)
2x - 1 = -15
Addition Property of Equality (Add 1 to both sides)
2x = - 14
Division Property of Equality (Divide both sides by 2)
x = -7
Just got it The answer is C 3.
Answer:
For part A the value of m is 2/5
Step-by-step explanation:
When a system equation has no solution it means a equation is parallel and it doesn't intersect. And when a line is parallel to one another it has the same slope.
Answer: you add them all up
Step-by-step explanation: you can get the answer from above and dont trust this answer.
Answer:
The y-intercept is 0, which represents the amount of gas used when 0 miles are traveled. The slope is 28, which represents the miles that can be traveled with 1 gallon of gas
Step-by-step explanation:
Let
x----> the amount of gas used in gallons
y ---> the distance traveled in miles
we have

This linear equation represent a direct variation
The y-intercept is the value of y when the value of x is equal to zero
For x=0, y=0
That means ----> The y-intercept is 0, which represents the amount of gas used when 0 miles are traveled
The slope is 
That means ----> The slope is 28, which represents the miles that can be traveled with 1 gallon of gas
