I think it’s y= -2/2x +2? Something like that I may be wrong lolz
Option B
The number of light years in
miles is 11508 light years
<em><u>Solution:</u></em>
Given that,
One light-year equals 5.9 x 10^12 miles
Therefore,

To find: Number of light years in
miles
Let "x" be the number of light years in
miles
Then number of light years in
miles can be found by dividing
miles by miles in 1 light year

Thus number of light years in
miles is 11508 light years
B; you can graph the function on a graphic calculator or use algebra find each of the desired aspects
let t = time (hrs) that they are 50 mi apart
Use pythag here; a^2 + b^2 = c^2; dist = speed * time
(30t)^2 (40t)^2 = 50^2
900t^2 + 1600t^2 = 2500
It's obvious that t = 1 hr
First question:
1. Set equations equal to each other so 5x-9=2x+6
2. Put x's on one side so that 3x=15
3. Divide by 3 so that x=15
4. Substitute 15 in for x so that y=2(15)+6
5. Solve for y so that y=36
6. Thus the equations intersect at (15,36)
Second question:
1. Since for lines y=mx+b, and m=slope=3 you only need to write an equation with slope 3
2. y=3x+b, b can be any number
