The answer is 11.
Step-by-step explanation:
19-25\19-15
44/4= 11
L = (1⅕)W= (6/5)W
LW = 480 in²
(6/5)W² = 480
W² = 480 × ⅚ = 400
W = 20 in
L = (6/5)W =24 in
14.6 is the constant because no matter how many hours she will work (that number could change) it will always be a linear growth of 14.6.
Find the length of the ladder if the distance from the bottom of the ladder to the building is 9 feet.
For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

Where:
m: It's the slope
b: It is the cut-off point with the y axis

We have the following points:

Substituting the values:
Thus, the line is of the form:

We substitute one of the points and find "b":

Finally we have to:

Answer:
The equation es
