Answer:
19. 125/3 20.625/3
Step-by-step explanation:The chance is 1/6 spins it will land on w so 1/6 times 250, 5/6 that it will not land on w so 5/6 times 250, and then you just simplify.

B
Step-by-step explanation:
The solutions are at (-2,0) and (1,-3)
Answer:
(x - 12)²/9
Step-by-step explanation:
y = 3sqr(x) + 12
Make x the subject:
y - 12 = 3sqrt(x)
(y - 12)/3 = sqrt(x)
Square both sides
(y - 12)²/9 = x
Interswitch variables
inverse function is:
(x - 12)²/9
If f(x) = (x + 12)^⅓
Then,
y = (x + 12)⅓
y³ = x + 12
y³ - 12 = x
f inverse:
x³ - 12
