Answer:
see explanation
Step-by-step explanation:
Find the zeros by equating h(x) to zero, that is
(- 4x - 3)(x - 3) = 0
Equate each factor to zero and solve for x
- 4x - 3 = 0 ⇒- 4x = 3 ⇒ x =- ![\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D)
x - 3 = 0 ⇒ x = 3
I'm going to take a guess on this one and say 1:30 p.m on October 25
we have
------> inequality A
The inequality A is the solid red line in the graph
the solution of the inequality A is the shaded area above the solid red line
------> inequality B
The inequality B is the solid blue line in the graph
the solution of the inequality B is the shaded area above the solid blue line
we know that
the point
lie on the line of the inequality B
substitute the values of x and y in the equation of the line
![x+4y = c](https://tex.z-dn.net/?f=x%2B4y%20%3D%20c)
![0+4*(-3) =c](https://tex.z-dn.net/?f=0%2B4%2A%28-3%29%20%3Dc)
![c=-12](https://tex.z-dn.net/?f=c%3D-12)
so
the equation of the line B is
![x+4y =-12](https://tex.z-dn.net/?f=x%2B4y%20%3D-12)
the equation of the inequality B is
![x+4y \geq -12](https://tex.z-dn.net/?f=x%2B4y%20%5Cgeq%20-12)
therefore
<u>the answer is</u>
The number is ![-12](https://tex.z-dn.net/?f=-12)
Simple...
you have: If this cable installer charges $42.50 per hour plus a fixed $45 service charge..then set your equation..using-->>
y=mx+b
How much would the cable installer charge for 5 hours?
y=42.50(5)+45
y=212.50+45
y=$257.50
Thus, your answer.
