If y=4 when x=12, find y when x=-24
goldfiish [28.3K]

The value of y is -8 if the x  -24 and y varies directly with x, and If y = 4 when x = 12.

<h3>What is a proportional relationship?</h3>

It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.

The question is incomplete.

The complete question is:

If y varies directly with x, and If y = 4 when x = 12, how do you find y when x = -24?

y ∝ x  (given)

y = kx

k is the constant of proportionality.

4 = 12k  (y = 4, and x = 12)

k = 1/3

y = x/3

Plug x = -24

y = -24/3

y = -8

Thus, the value of y is -8 if the x  -24 and y varies directly with x, and If y = 4 when x = 12.

Can someone please help me am failing
Elena-2011 [213]
Part A: W= Wage (money earned)
$6 (earned per hour without working overtime)     Equation: W=$6x
x= number of hours

S= (money earned)
$6 plus $9 (earned per hour with working overtime) Equation S=$15y
y= hours

Part C: Use S=$15y   (this shows the amount of money earned after working overtime after the certain amount of hours spent)

$330=$15y

I think you can solve from there
