To solve this, all we need to do is substitute the values of x and y at which they are the same into each equation and see if it holds true.

A. (y)/(x) = (1)/(2)

(-8)/(4) = (1)/(2)

-2 = (1)/(2)

Since this is not true, we can scratch choice A off our list.

B. (y)/(x) = -2

(-8)/(4) = -2

-2 = -2

This is true, so choice B is one of the correct answers.

C. -2x = y

-2 (4) = -8

-8 = -8

This equation also holds true, so choice C is also correct, but let us do the final option just for the sake of completion.

D. x = 2y

4 = 2 (-8)

4 = -16

This is obviously not true, so choice D is also false.

The correct answer choices are B and C.
Hope that helped! =)
varies directly, so x times a number = y
let z be that number
y= zx
-8=4z
z=-2
y=-2x
which is equals to y/x=-2 and -2x=y , so its B and C

Any help is welcome :) only right answers get brainilest

Explicit rule formula: a(n) = a · rⁿ⁻¹

a(n) = ⁿth term

a = first term

r = common ratio

ⁿ⁻¹ = the previous term

In the recursive rule a₁ = 2/3; aₙ = 9 · aₙ₋₁ the first term is 2/3 and the common ration is 9. We can fill in the explicit formula with what we know.

Thus, the correct answer is [ aₙ = 2/3 · 9ⁿ⁻¹ ]

Best of Luck!

Answer:

a_(n) =(2)/(3)*9^(n-1)

Step-by-step explanation:

a1 = 2/3

an = 9*a(n-1)

a2 = 9 *a1 = 9* 2/3

a3 =9*a2 = 9 *(9*2/3) = 9²*2/3

a4 = 9*a3 = 9* (9²*2/3) = 9³*2/3

During a sale 36 similar handbags are sold for a total of $1,620. Before the sale, the same number of handbags were sold at $49 each. What is the difference between the amount if money before and after the sale?

Answers

Hey there!

Here are the steps involved in answering this question:

1. We know that 36 handbags were sold for $1620 during the sale. 

2. We want to know how much money they earned by selling 36 handbags for 49 dollars each. 

Steps:

1. Since 36 handbags were also sold before the sale, multiply 49 by 36.

36 x 49 = 1764

They earned $1764 before the sale. 

Now, find the difference between each of the sales.

1764 - 1620 = 144

Answer: $144

jasmines cd collection is 3/8 jazz 1/4 rap and the rest is rock music what is the fraction of rock music

Answers

rap - 1/4
jazz - 3/8
rock - x
all - 1


jazz + rap + rock = all

3/8 + 1/4 + x = 1
3/8 + 2/8 + x = 1
5/8 + x = 1
x = 1 - 5/8
x = 3/8

answer: rock - 3/8

a- all\n j-jazz\n r_a-rap\n r_c-rock\n\n a=j+r_a+r_c\Rightarrow r_c=a-j-r_a\n\n r_c=1-(3)/(8)-(1)/(4)\n\n r_c=1-(3)/(8)-(2)/(8)\n\n r_c=(8)/(8)-(3)/(8)-(2)/(8)\n\n r_c=(3)/(8)
