Answer:
72
Step-by-step explanation:
Area = base * height
Area = 9 * 8 = 72
-20=-4x-6x
First combine like terms.
-20=-10x
Divide by -10 on both sides
X=2
6/6 but it simplifies to 1
Answer:
Part A:
I have attached the graph of this system of inequalities.
Part B:
Plug in (8,10) into both equations
10 > 3(8) + 10
10 > 24 + 10
10 > 34
This is false!
10 < (-3/4)(8) - 1
10 < (-3)(2) - 1
10 < -6 - 1
10 < -7
This is also false!
So, (8,10) is not included in the solution area for the system.
