Answer: 1:10,000

Step-by-step explanation:

given data:

distance of the nearest star system = 100,000,000

distance to size ration of the sun earth system = 10,000

therefore;

100,000,000 / 10,000

= 10,000

The order of magnitude of the distance to size ratio of the Sun- Nearest Star system is about 1:10,000 times that of the Sun-Earth system.

Write an equation of the form y = mx for the line shown below. If appropriate,

9966 [12]

Answer:

y = - 0.5x

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 4, 2) and (x₂, y₂ ) = (2, - 1) ← 2 points on the line

m = $\frac{-1-2}{2-(-4)}$ = $\frac{-3}{2+4}$ = $\frac{-3}{6}$ = - 0.5

The line crosses the y- axis at (0, 0 ) ⇒ c = 0

y = - 0.5x + 0 . that is

y = - 0.5x

A lumberyard will deliver wood for $7 per board foot plus a delivery charge of $10. Find a function C(x) for the cost (in dollar

Paladinen [302]

Answer:

C(x) = 7x + 10

Step-by-step explanation:

If the delivery charge is $10 for any number of board feet ordered.

If the delivery charge is $10 for each board feet ordered, the function would

be C(x) = (7 + 10)x = 17x
