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

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

3x-8<23 and -4x+26>6

Papessa [141]

Answer:

3x-8<23 and -4x+26>6

x<31/3 x<5

Step-by-step explanation:

3x-8<23

Add 8 to both sides

3x<31

Then divide 3 to both sides

x<31/3

and -4x+26>6

Minus 26 to both sides

-4x>-20

You divide -4 to both sides

Keep in mind that everytime you divide a negative the inequality will change so > will be <

x<5
