If our galaxy were 1m wide, what would the distance to the Andromeda Galaxy be?

Setler79 [48]

Answer:

25 m

Step-by-step explanation:

The scale factor is

1 : 9.5×10²⁰ as we make our galaxy as small as 1 m.

The distance to Andromeda would be:

2.4×10²² * 1/9.5×10²⁰ =
2.4/9.5×10²²⁻²⁰ =
0.25×10² =
25 m

(-2,0) and (3,4) slope=1/3 and (2,4) SOLVE EQUATIONS FOR THEM PLEASE

andrew11 [14]

Answer: $a)\quad y=\dfrac{4}{5}x+\dfrac{8}{5}$ $b)\quad y=\dfrac{1}{3}x+\dfrac{10}{3}$

Step-by-step explanation:

Use the Slope formula: $m=\dfrac{y_2-y_1}{x_2-x_1}$

and the Point-Slope formula: y - y₁ = m(x - x₁)

a) (-2, 0) and (3, 4)

$m=\dfrac{0-4}{-2-3}\quad =\dfrac{-4}{-5}\quad =\dfrac{4}{5}$

Let (x₁, y₁) = (-2, 0)

y - y₁ = m(x - x₁)

$y-0=\dfrac{4}{5}\bigg(x-(-2)\bigg)\\\\\\y\quad =\dfrac{4}{5}\bigg(x+2\bigg)\\\\\\\large\boxed{y\quad =\dfrac{4}{5}x+\dfrac{8}{5}}$

b) m = 1/3 (x₁, y₁) = (2, 4)

y - y₁ = m(x - x₁)

$y-4=\dfrac{1}{3}\bigg(x-2\bigg)\\\\\\y-4 =\dfrac{1}{3}x-\dfrac{2}{3}\\\\\\y\quad \ =\dfrac{1}{3}x-\dfrac{2}{3}+\dfrac{12}{3}\\\\\\\large\boxed{y\quad =\dfrac{1}{3}x+\dfrac{10}{3}}$

Solve. 7x − 2 = −23 x =

Zielflug [23.3K]

7x-2=-23 add 2 to both sides to get 7x by itself
7x=-23+2 now add the right side
7x=-21 now divide both sides by 7
x=-21/7
x=-3
