A = (1/2)(x)(y)
Let x = diagonal 1
Let y = diagonal 2
The product of xy = 144.
This means that x = 12 and y = 12.
So, 12 • 12 = 144
Each diagonal is 12 feet.
Prove:
72 feet = (1/2)(12)(12) feet
72 feet = (1/2)(144) feet
72 feet = 72 feet
Personally I'd solve this inequality for y first: y < x-3.
That immediately eliminates (6,2) and (2,6).
Starting from y < x-3 and letting 2 sub for x and -1 sub for y, is the following true or false?
-1 < 2 -3 NO. -1 < -1 is false. Was there a fourth answer choice?
1. Turn improper
2. set up the problem

Answer:
This means that the cost of 2 heating oil gallons is 14.
Step-by-step explanation:
f(x) = 4x + 6 , where x is the number of heating oil gallons.
And f(x) = 4x + 6 is the equation for the cost of x gallons.
When the number of gallons are 2 then the cost is;
f(2) = 4(2) + 6 = 8 + 6 = 14
This means that the cost of 2 heating oil gallons is 14.
