Saini Sprinkler Company installs irrigation systems. To track monthly costs C and revenues R, they use the following functions, where x is the number of systems they install. R(x)=8x^2+12x+4

C(x)=7x^2+20x-12

The monthly profit can be found by subtracting cost from revenue.

P(x)=R(x)-C(x)

Find a function to project monthly profit and then use it to find the break-even point where the profit is zero.

1. m=1

2. m=0, 1

3. h=8

4. h=11, 17

Step-by-step explanation:

The variables stand for numbers. Replace the variables with any of the given numbers to make the equation or inequality true.

1. 1+5=6, so m=1

2. 0+5=5. 5<6. 1+5=6. 6=6. The symbol ≤ is "less than or equal to", so m=0 or m=1.

3. 5*8=40. h=8.

4. 5*11=55. 55>40. 5*17=85. 85>40. h=55 or h=85.
