Answer:
2
Step-by-step explanation:
It is saying that both equations equal each other, as they both equal f(x). So we just move each of the factors to equal each other. Like 3x+5=11. There you just subtract the 5 from both sides to get 3x=6, and then divide both sides by 3 to get x=2.
You have to average out the total amount you pay by how many movies you see. For this deal, you must spend $16 (4 movies x $4) to get a fifth movie free. So, you are essentially spending $16 for 5 movies. To figure out how much the cost is per movie, divide the total cost by number of movies seen. $16/5 movies = $3.20 per movie
Answer:
3u-40+2u = 6u-30-u
On simplifying
5u-40= 5u-30
5u+0y-40 = 5u+0y-30 (Infinitely many solutions)
Answer:
B
Step-by-step explanation:
Ab*h= 3*2*5= 30
which is B

f(x)=19x+2→ Switch the f(x) with a y
y=19x+2→ Switch the places of the x and the y variables
x=19y+2→ Solve for y
x−2=19y
y=9x−18
The inverse is f−1(x)=9x−18
