If y ∝ 1∕x and y = –2 when x = 14, find the equation that connects x and y. A) y = –28x
B) y = –7x
C) y = –28∕x
D) y = –7∕x

C

Step-by-step explanation:

Given y ∝ then the equation relating them is

y = ← k is the constant of variation

To find k use the condition y = - 2 when x = 14 , then

- 2 = ( multiply both sides by 14 )

- 28 = k

y = - ← equation of variation

step- i d k and i d c : )

you: : 0

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
