Answer:
daffodil = $13 Tulip = $7
Step-by-step explanation:
6t + 12d = 198
7t + 6d = 127
6t = 198 - 12d
t = 33 -2d
substitute
7(33-2d) + 6d = 127
231 -14d +6d = 127
- 8d = -104
d =13
6t + 12(13) = 198
6t +156 = 198
6t = 42
t = 7
Answer:
1/3x - 3
Step-by-step explanation:
To find the inverse, we exchange x and y and then solve for y
y =3x+9
Exchange x and y
x = 3y+9
Then solve for y
Subtract 9 from each side
x-9 =3y+9-9
x-9 = 3y
Divide by 3
1/3(x-9) = 3y/3
1/3(x-9) = y
Distribute
1/3x-3 = y
The inverse is 1/3 x -3
The answer is 88 cube units.
