Answer: C (x=1)
Step-by-step explanation:
f(x)=0 at points of intersection of the graph of the function with x-axis.
The graph of the function intersects x-axis at three points:
somewhere between -3 and -2;
somewhere between -1 and 0;
at x=1.
Since x=1 is the value of x from the domain, then correct choice is option C.
Okay, the answer for the first problem is -24x-54. The second is -12k^4-16k^3+20k^2. Finally. the third one is -24x^3. Hope you get it.
3/4 of 12 is 9
12 - 9 =3
3 sections are left
The problem says the car travels 340 miles on 20 gallons so 340/20
We want to know how much the car can travel with 25 gallons of gas so x/25
We would use cross multiplication:
![\frac{340}{20} = \frac{x}{25}](https://tex.z-dn.net/?f=%20%5Cfrac%7B340%7D%7B20%7D%20%3D%20%20%5Cfrac%7Bx%7D%7B25%7D%20%20)
From here you would multiply:
![340*25 =20x](https://tex.z-dn.net/?f=340%2A25%20%3D20x)
Now to solve for x you would start by multiplying 340 * 25
340*25=8500
now we have
8500=20x
to isolate x we would divide both sides by 20
Final answer: x=425miles
So the answer is 425miles
