Which equation(s)

aleksandrvk [35]

Answer:

C) y = 12 x Represents the proportional relationship.

Step-by-step explanation:

Two quantities P and Q are said to be proportional if and only if:

$P \propto Q \implies P = k Y$

Here: K = Proportionality Constant

Now, here the given expression are:

$1. y = 7 x^2\\\implies y \neq kx$

So, y is NOT PROPORTIONAL to x.

$2. y = 2 + 3x\\\implies y \neq kx$

So, y is NOT PROPORTIONAL to x.

$3. y = 12 x\\\implies y = kx, k = 12$

So, y is PROPORTIONAL to x.

$2. y = 5 - x\\\implies y \neq kx$

So, y is NOT PROPORTIONAL to x.

poizon [28]

Answer:

The quantity of ground meat he use for hamburgers is 2 $\frac{13}{80}$ pounds

Step-by-step explanation:

Given as :

The total quantity of ground meat bought to make hamburgers = 2 $\frac{9}{16}$

Or, The total quantity of ground meat bought to make hamburgers = $\frac{41}{16}$ pound

The quantity of ground meat left after use = $\frac{2}{5}$ pound

Now, let The quantity of ground meat used for hamburgers = x pound

So, x = The total quantity of ground meat bought - The quantity of ground meat left

Or, x = $\frac{41}{16}$ pound - $\frac{2}{5}$ pound

Or, x = $\frac{205-32}{80}$ pound

I.e x = $\frac{173}{80}$

∴ x = 2 $\frac{13}{80}$ pounds

Hence The quantity of ground meat he use for hamburgers is 2 $\frac{13}{80}$ pounds . Answer
