Answer:
2x^2x(x^+3x-2)
Step-by-step explanation:
Answer:
5y = -2x + 31
Step-by-step explanation:
Given equation:
y = 
Coordinate = (-7,9)
Unknown:
Equation of the line perpendicular = ?
Solution:
The slope - intercept format of a line is given as;
y = mx + c
where y and x are the coordinates
m is the slope
c is the y-intercept
y = 
From the given equation; slope is 
A line perpendicular will have a slope that is negative and the inverse of this;
slope of perpendicular line = 
Since y= 9 and x = -7;
So;
9 =
+ C
9 =
+ C
C = 9 -
= 
Now,
y =
x + 
mulitply through by 5;
5y = -2x + 31
The solution to this is 3(8)-3(9).
Increase.
1/4 can be translated to 25%
1/2 can be translated to 50%
25% to 50% is an increase.
