Theres 8 edges, 5 vertices, and 5 faces.
From inspecting the graph, you can identify the y-intercept and the slope of the line shown.
The y-intercept is 200 gallons.
The slope is
75-200
m = ------------- = -12.5 gallons/minute
10 - 0
Thus, y = 200 gallons - [12.5 gallons/minute ]t
To answer the 2nd question, let t = 12 minutes and calculate y(12).
To determine how long it wld take to empty the tank, set the above formula equal to zero and solve the resulting equation for t.
Step 1:
(3,6) means x coordinate is 3 and y coordinate 6
Step 2:
We substitute the values of x = 3 and y = 6 into the inequality

Conclusion:
Since 6 is equal to 6, then (3,6) is a solution of the given Inequality
To find each box, you have to multiply the number above the box and the number to the left of the box.
For the bottom left, we have 4 x 0.8 or 3.2.
For the bottom right, we have 0.8 x 0.6 or 0.48.
In the given formula :
r = rate = 4.5% = 0.045
t = time = 7 years
P = principal = #3,700
e is an arbitrary number used in mathematics, which is approximately 2.7183
Replace the letters with the given information:
A = 3700e^0.045(7)
A = $5,069.96
The answer is C
