Hello,
f(x)=2x^3-x^2-4x+9=(((0+2)x-1)x-4)x+9
f(3)=(((0+2)*3-1)*3-4)*3+9=((2*3-1)*3-4)-3+9=(5*3-4)*3+9=11*3+9=33+9=42
or
f(3)=2*3^3-3^2-4*3+9=2*27-9-12+9=54-12=42

Answer:</h3>
The radius would be <em>3.5 units</em>.
Step-by-step explanation:
This is because a radius is always half of a diameter.
By using that,
7 ÷ 2 = 3.5 units
Since there was no measurement listed in the question, the answer would be in "units."
I think is 192 but I'm not sure
There is one solution.
Just divide the 2nd line by two to get -2x + y= 3, then put it in slope-intercept to get y= -2x + 3
THen
y=2x+3
y= -2x + 3 subtract
4x=0
so x=0
plug in 0 for x
y= 2(0) +3
so y =3.
plug in to check
3=0+3 checkmark
-4(0) +2(3) = 6 checkmark
