Undefined means it goes through the x intercept, x=3
Answer:
x = 2
Step-by-step explanation:
y = - 5 is a horizontal line parallel to the x- axis.
A line perpendicular to it will be a vertical line parallel to the y- axis with equation
x = c
Where c is the value of the x- coordinates the line passes through.
The line passes through (2, 7) with an x- coordinate of 2, thus
x = 2 ← is the equation of the perpendicular line
Ok well...
1200 times .25 is 300 so subtract 1200-300= 900 is the decreased number :)
Hope it helps! :)
