x × 1.1 × 1.1 × 1.1 × 1.1 = 20,000

x × 1.4641 = 20,000

x= \frac{20,000}{1.4641}

x = $13660.27

Write a linear equation based on given information. Through (5,-5) and (4,0)
Katena32 [7]

For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

y = mx + b

Where:

m: It is the slope of the line

b: It is the cut point with the y axis

We have the following points:

(x_ {1}, y_ {1}) :( 5, -5)\\(x_ {2}, y_ {2}) :( 4,0)

We find the slope:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {0 - (- 5)} {4-5} = \frac {5} {- 1} = - 5

Thus, the equation is of the form:

y = -5x + b

We substitute a point and find b:

0 = -5 (4) + b\\0 = -20 + b\\b = 20

Finally, the equation is:

y = -5x + 20

Answer:

y = -5x + 20

Answer:

Step-by-step explanation:

If 3/4 of the lot was full and the lot holds 1000 vehicles, then there are 3/4(1000) in the lot.  3/4(1000) = 750.  That means there are 750 vehicles in the lot.  If 200 cars are in the lot, then 750 - 200 = 550 trucks.
