Answer:

since the line goes through the origin you dont need a y intercept.

y= x/2

The total weight of a rock depends on its size and is proportional to its density. In this context, density is the weight per cu

kow [346]

Answer:

$d = \frac{w}{48}$

If $\frac{1}{48} \\$ is constant, say k

Then,

$d = kw$

∴ d ∝ w

Hence, weight is proportional to the density

Step-by-step explanation:

From the question,

Let w denote the weight of the rock in pounds

s denote the size of the rock in cubic inches and

d denote the density of the rock in pounds per cubic inch.

First, we will write the equation connecting w, s, and d.

We get

$density (pounds/inch^{3} ) = \frac{weight(pounds)}{size (inch^{3}) }$

That is,

$d = \frac{w}{s}$

Now, given a 48-cubic-inch rock with weight w pounds, to show the proportional relation between the weight and the density, we will write

$d = \frac{w}{48}$

If $\frac{1}{48} \\$ is constant, say k

Then,

$d = kw$

∴ d ∝ w

Hence, density is proportional to the weight OR weight is proportional to the density

Alkena and Hsu together earn $84,369 per year, If alkena earns $12,468 more per year than Hsu, the how much of them earn per yea

scoray [572]

Answer:

Hsu makes $35,950.50 and Alkena makes $48,418.50

Step-by-step explanation:

Create a system of equations, where h is the amount Hsu makes and a is the amount Alkena makes:

a + h = 84,369

a = h + 12,468

Solve by substitution by plugging in h + 12,468 as a:

h + 12,468 + h = 84,369

2h + 12,468 = 84,369

2h = 71,901

h = 35,950.50

Plug this into the equation, a = h + 12,468 , to solve for a

a = 35,950.50 + 12,468

a = 48,418.50

So, Hsu makes $35,950.50 and Alkena makes $48,418.50
