I would do it this way
$780+$225=$1005
$1005/120ft= $8.375
if you have to round up $8.38 per foot
Answer:
The answer to your question is letter B
Step-by-step explanation:
Process
1.- Find two points of each line
Line A (-2, 0) (-1, 2)
Line B (-1. - 5) (-6, 0)
2.- Find the slope and equation of each line
Line A


m = 2
y - 0 = 2(x + 2)
y = 2x + 4
Line B


m = -1
y - 0 = -1(x + 6)
y = -x - 6
3.- Find the inequalities
Line A, we are interesteed in the lower area of the line, so the inequality is
y ≤ 2x + 4
Line B, we are also interested in the lower area of the line so the inequality is
y ≥ - x - 6
The zero property is anything multiplied zero to equal zero
Answers: A and D
-4.7x0=0
0x3=0
Answer:
x=0, - 9
Step-by-step explanation:
x^2+9x=0
x(x+9)=0
x=0 or x=-9
