Is 9-8x=y proportional
andrew-mc [135]

Answer:

No, proportional relations are of the form,

y = mx

Step-by-step explanation:

The given equation is

9 - 8x = y

This is an equation in the form:

y = mx + c

since we can rewrite to get:

y =  - 8x + 9

This equation has a non-zero y-intercept and does not pass through the origin.

A proportional relation, will have a zero y-intercept and pass through the origin.

Therefore a proportional relation is of the form,

y = mx

The length of the subway is 850 miles. If .15 inch represents 45 miles, what is the length of the subway on the map?
Scilla [17]

Answer:

The length of the subway on the map is 2.83\ inches

Step-by-step explanation:

we know that

The scale on the map is equal to the length of the subway on the map divided by the length of the subway in the actual

so

Let

z------> the scale on the map

x------> the length of the subway on the map

y------> the length of the subway in the actual

z=\frac{x}{y}

In this problem we have

z=\frac{0.15}{45}\frac{inches}{miles}

y=850\ miles

substitute and solve for x

\frac{0.15}{45}=\frac{x}{850}

x=850*\frac{0.15}{45}=2.83\ inches
