6. i cant see number 6 so yah
Step-by-step explanation:
X=9
You would do 54 divided by 5x and it would equal to 9 that means x is 9
Its a simultaneous equation:
lets make "x" the used games and "y" the new ones
4x + 2y = 84
6x + y = 78. (multiply this by 2 to cancel out y)
12x + 2y = 156
so now we subtract them:
12x - 4x = 156 - 84
x = 9
used games cost $9
new games cost 78 - 6(9) = $24
Janet has $120 but she already bought 3 NEW games so:
120 - 3(24) = $48 left
48/9 = how many used ones she can buy = 5. something
she can buy 5 used

Answer:
Step-by-step explanation:
We are given these following functions:
The first step to solve this question is finding the composite functions. So
At x = 2
Now we replace x by 2 in each of the functions. So
