Situation 1: Kayla has $30 to spend on yogurt. She spends a total of $6 each day on yogurt.

Situation 2: Andy has 5 discus fish. He purchases 3 more each week for $8 each.
In Situation 1, which rule models the total amount that Kayla has left to spend on yogurt (c) as a function of the number of days (d)?

b. astronomers

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

1/4 because there is 4 grades.
