if y is directly proportional to x when x = 4 and y = -2, write an equation to model the given relationship. What is x if y = -2
hoa [83]

Direct proportion equations have the following form:

y=kx

Where "k" is the Constant of proportionality.

In this case you know that "y" is directly proportional to "x" and when:

x=4;y=-2

Having these values, you can substitute them into the equation and solve for "k":

\begin{gathered} -2=k(4) \\ \frac{-2}{4}=k \\ k=-\frac{1}{2} \end{gathered}

So, substituting the value of "k" into the first equation shown above, you get that the equation that models the given relationship is:

y=-\frac{1}{2}x

Now, to find the value of "x", when the value of "y" is -24, you must substitute this value into the equation that models the relationship and then solve for "x". Then, you get:

\begin{gathered} -24=-\frac{1}{2}x \\ (-24)(-2)=x \\ x=48 \end{gathered}

Therefore, the answers are:

\begin{gathered} y=-\frac{1}{2}x \\  \\ x=48 \end{gathered}

Pls can any one solve this​
belka [17]

All the angles make a full circle which needs to equal 360 degrees.

Add all the angles together to equal 360:

X + (x-10) + (4x-20) +(2x-10) + (x +10) = 360

Combine like terms:

9x -30 = 360

Add 30 to both sides:

9x = 390

Divide both sides by 9:

X = 390/9

X = 43.3333. ( 43 and 1/3)

Renate wins a $20 gift card to an online music site. After Renetta purchased 16 songs, the gift card has a remaining balance of
uysha [10]

Answer:

b. 5x + 4y = 80

Step-by-step explanation:

Let us assume the remaining balance left be Y

and, the number of songs purchased be X

Given that

Wins a gift card of $20

And, the songs purchased is 16

Now if we take the fraction

= 20 ÷ 16

= 5 ÷ 4

So if we reverse this fraction

So it could be 5x and 4y

And, the amount that would come is

= $20 × 16 ÷ 4

= 80

So, the equation is 5x + 4y = 80

Hence, the correct option is b.
