Answer:
first 2/21 2nd 4/43
Step-by-step explanation:
1. As you can see in the figure attached in the problem, you have the following system:
y≥5x-4 (i)
y≤5x/6 (ii)
2. When you solve the system, the values of the variables "x" and "y", are:
x=24/25
y=4/5
3. When you graph the system, you obtain the graph shown in the image attached.
Answer: -77x^2 - 84x
Step-by-step explanation:
-7x ( 11x +12)
-77x^2 - 84x
Answer:
10x^2 + 12x + 14
Step-by-step explanation:
Combine like terms: 2x^2 + 8x^2 = 10x^2 , 9x + 3x = 12x , 12 + 2 = 14
In total: 10x^2 + 12x + 14
