Answer:

Correct choce is (a). 30.

Step-by-step explanation:

Given equation is $f(x)=x^2-x$ .

Now we need to find the value of (fof)(3). Then select correct matching choice from the given choices. Where given choices are:

(a). 30

(a). 33

(a). 6

(a). -6

Now let's find $(fof)(3)$

$(fof)(3)=f(f(3))$

$(fof)(3)=f(3^2-3)$

$(fof)(3)=f(9-3)$

$(fof)(3)=f(6)$

$(fof)(3)=6^2-6$

$(fof)(3)=36-6$

$(fof)(3)=30$

Hence correct choce is (a). 30.

tensa zangetsu [6.8K]

Answer:

(x, y) =(2,-3)

Step-by-step explanation:

4x+3y=-1

3x-9y=33 /:3

4x+3y=-1.....(1)

x-3y=11... (2)

(1)+(2): 5x=10

x-3y=11

x=10/5

x-3y=11

x=2

2-3y=11

x=2

-3y=11-2

x=2

-3y=9

x=2

y=9/(-3)

x=2

y=-3

(x,y)=(2,-3)
