Plug in the x+3 for y.
8x-x+3=12
7x=9
X=1.3
Then, y= -0.25
f(x) represents the total number of pages Antonia has read; x represents the number of days
Replace F(x) with y
y=x^3-10x^2+24x
To find the roots replace y with 0.
0=x^3-10x^2-24x
Rewrite the equation as
x^3-10x^2+24x=0
Factor the left side
x(x-6)(x-4)=0
The solution is a result of
x=0, x-6=0, and x-4=0
The answer is:
x=0, 6, 4
Morgan is right because to find how much something is per minute you need to divide. In this case, you need to divide 68 and 8. The answer then is 8.5
