Answer:
The distance from 68 miles to 42.5 miles decrease .
The Percentage of change is 37.5% .
Step-by-step explanation:
Formula
Where
Change in value = |Final value - Initial value|
As given
68 miles to 42.5 miles .
Thus the distance decrease .
Final value = 42.5 miles
Initial value = 68
Change in value = |42.5 - 68|
Change in value = |-25.5|
Change in value = 25.5
Putting all values in the formula
Percentage change = 37.5 %
Therefore the Percentage of change is 37.5% .
In the point-slope form of a line, (y-y1)=m(x-x1)
'm' represents the slope of the line.
(x1,y1) represents a given point on the line.
(x,y) represents any point on the line.
The equation of a straight line that passes through a particular point and is inclined at a specific angle to the x-axis can be found using the point slope form.
A straight line is represented using its slope and a point on the line using point slope form. This means that the point slope form is used to determine the equation of a line whose slope is "m" and passes through the point (x1,y1).
The point slope form's equation is (y-y1)=m(x-x1), where (x, y) is a randomly chosen point on the line and m is the slope.

They have the same measurements but they are turned different ways
Answer:
x^2+2x
Step by step explanation:
(2x^2+3x)-(x^2+x)
Remove unnecessary parentheses
2x^2+3x-(x^2+x)
When there is a - in front of an expression in parentheses, change the sign of each term of the expression and remove the parentheses
2x^2+3x-x^2+x
Collect like terms
x^2+3x-x
