If f(x)=-x^2+6x-1 and g(x) =3x^2-4x-1, find (f-g)(x)

asambeis [7]

Answer:

Step-by-step explanation:

Given,

$f(x)=-x^{2} +6x-1\\g(x)=3x^{2} -4x-1$

we know,

(f-g)(x)=f(x)-g(x)

So, here we get

(f-g)(x)

=f(x)-g(x)

= $-x^{2} +6x-1-(3x^{2} -4x-1)$

= $-x^{2} +6x-1-3x^{2} +4x+1$

= $-x^{2}-3x^{2} +6x+4x-1+1$

= $-4x^{2} +10x$

So, the answer is

$-4x^{2} +10x$

Miles brought the Russian novel Anna Kerenina. His paperback edition contains 992 page. Miles takes 3 days to read the first 50

Nesterboy [21]

Answer:

59.52 days

Step-by-step explanation:

So this is a simple problem we can solve easily

If it takes 3 days to read 50 pages then obviously his rate of reading is 50 pages per day

If we divide 992 by 50, then we can find how many 3 day increments it will take him

(992/50 is 19.84)

Now is we multiply 19.84 by 3, we get the total amount of days which is 59.52

I hope I helped and have a wonderful day!
