Answer:
y = 6x + 9
Step-by-step explanation:
The equation of a line in slope- interceot form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 2x + 12y = - 1 into this form
Subtract 2x from both sides
12y = - 2x - 1 ( divide all terms by 12 )
y = -
x -
← in slope- intercept form
with slope m = - 
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= 6
Note the line passes through (0, 9) on the y- axis ⇒ c = 9
y = 6x + 9 ← equation of perpendicular line
Answer:
B.
Step-by-step explanation:
300.50(0.07)= 21.04
300.50+21.04= 321.54 321.54x = 900.85 x = 2.8
12.78 because if you do ( 12 X .065 you get .78 which you then add to 12$ and get a total of 12.78
If my calculations are correct the answer is 21 ft
