Answer:

Yes, x^2 + 2y = 4 is a function.

Step-by-step explanation:

x^2 + 2y = 4

Solve for y.

2y = -x^2 + 4

y = -(1/2)x^2 + 2

f(x) = -(1/2)x^2 + 2

Answer: Yes, x^2 + 2y = 4 is a function.

Tobias rented a kayak from a sports equipment store.

Ket [755]

Answer:

B

Step-by-step explanation:

Let x = every day he rented the kayak

Since the store charges $60 for each day, multiply x by 60 like this: 60x

They also have $25 on top of that; 60x + 25

This all has to equal $325; 60x + 25 = 325

To solve for x, subtract 25 from both sides

60x + 25 = 325

- 25 - 25

60x = 300

Divide both sides by 60

60x/60 = 300/60

x = 5

This means Tobias rented the kayak for 5 days
