The statement suppose <span>that y varies directly with x is best represented as:
y </span>α x
To make it into equality, we insert a proportionality constant, k:
y= kx
Using the initial conditions, we solve for k.
y= kx
<span>y = 25 when x = 140
</span><span>
25 = k(140)
k = 5/28
Thus, when </span><span>y = 36</span><span>,
</span>
36 =5/28x

Answer:ghfgh
Step-by-step explanation:gggjxg
3x - 4y = -4
3x - 3x - 4y = -4 - 3x
-4y = -4 - 3x
<u>-4y</u> = <u>-3x - 4</u>
-4 -4
y = 0.75x + 1
<u>D:{8, 4, 0, -4, -8}</u><u> </u>

y = 0.75x + 1
y = 0.75(8) + 1
y = 6 + 1
y = 7
