6+8+4+2=20
2/20 to grab mango can = 1/10
8/19 (remove one for previous) fro grape juice
6/18 for apple juice = 1/3
1/10*8/19*1/3
=
8/570
=
4/285
-6 + 7 = 1 and -6*7 = -42
So f(x) = (x + 7)(x - 6)
These require you solve for y. Do that by subtracting the x-term, then dividing by the y-coefficient.
5. 3y = 7x -9
y = (7/3)x -3
6. 6y = -2x -3
y = (-2/6)x -3/6
y = (-1/3)x -1/2
7. 8y = 2x + 12
y = (1/4)x +3/2
Yes, the input and output are both possible.
Reason~
Given that the possible solution is (20,20),
<u>Input</u> = x = 20
<u>Output</u> = x = 20
Thus, g(20) = 20, which is clearly possible.
