Answer:
Part 1) The slope is 
Part 2) The slope is 
Part 3) The slope is 
Step-by-step explanation:
Part 1) we know that
The equation of the line into slope intercept form is equal to
where
m is the slope
b is the y-coordinate of the y-intercept
In this problem we have
so
the slope is
Part 2) we know that
The equation of the line in standard form is equal to
where
the slope is equal to 
in this problem we have
so
substitute
Part 3) we know that
The formula to calculate the slope between two points is equal to
we have
Substitute the values
Answer:
-12π
Step-by-step explanation:
<span>Simplifying
2x + n = 3
Reorder the terms:
n + 2x = 3
Solving
n + 2x = 3
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '-2x' to each side of the equation.
n + 2x + -2x = 3 + -2x
Combine like terms: 2x + -2x = 0
n + 0 = 3 + -2x
n = 3 + -2x
Simplifying
n = 3 + -2x</span>
Answer
No. The amounts of change are the same, but the original amounts are different. The ratio for the percent increase from 50 to 70 is 20/50, or 40%. The ratio for the percent decrease from 70 to 50 is 20/70, or about 29%.
Answer:
$20
Step-by-step explanation:
<em>20% is equal to 20/100 therefore, if 5 x 20 is 100, you would multiply 5 x 4 and get 20, </em>
the reason you don't subtract the $4 is because it says "was" so the answer is $20
