F-1(x) is the inverse of f(x)

The domain of f(x) = range of f(-1)x and vice-versa.

So f-1(12) = 1.

marin [14]

Answer:

544

Step-by-step explanation:

The ratios of cartons are ...

B : P = 2 : 1

S : L = 2 : 1

L : B = 2 : 1

Combining these into a single set of ratios, we have ...

S : L : B : P = 8 : 4 : 2 : 1

Then the proportion of the order that is strawberry is ...

8/(8+4+2+1) = 8/15

and the number of strawberry cartons is ...

(8/15)·1020 = 544

The store ordered 544 cartons of strawberry yogurt.

Question: A canary's beak is, at most, 20mm long. Which algebraic inequality represents this situation?

Paul [167]

Answer:

Option (1).

Step-by-step explanation:

Statement given states that "A canary's beak is, at most 20 mm long."

Word "at most" means "the maximum".

So at most length of the beak means "length of the beak is less than equal to 20 mm".

And the expression representing this statement algebraically will be,

x ≤ 20

Therefore, option (1) will be the correct option.
