Answer:

AX : XB as AB : AC

AX = 5

XB = 4

AC = 6

AB = x

Step-by-step explanation:

5 : 4 as to x : 6

ratios can also be written as fractions...

5/4 = x/6 ..now we have a proportion...so we cross multiply

(4)(x) = (5)(6)

4x = 30

x = 30/4

x = 15/2 <==== AB = 15/2

Write the standard form of the equation of the line passing through (0, 1) and parallel to x = 4.

Savatey [412]

Answer:

x=0

Step-by-step explanation:

The line x=4 is a vertical line through the x-axis at 4. A line parallel to it will also be a line through the x-axis. It has the form x=a where a is the x-coordinates of any points on the line. Since the line crosses through (0,1), the equation is x=0.

Mercury is the closest planet to the sun at a distance of 36 million miles. The closest star to the sun is Proxima Centauri, whi

borishaifa [10]

Answer:

Proxima Centauri is 2.478 x 10¹³ miles from Sun.

Explanation:

Distance of Proxima Centauri to sun = 4.24 light years

1 light year = 5.9 x 10¹² miles.

Distance of Proxima Centauri to sun in miles = Distance in light years x 5.9 x 10¹² miles

So, Distance of Proxima Centauri to sun in miles = 4.2 x 5.9 x 10¹² miles

= 2.478 x 10¹³ miles

So Proxima Centauri is 2.478 x 10¹³ miles from Sun.
