Answer:
see below
Step-by-step explanation:
Each reflection is along a line through the other focus of the conic. The two foci of the parabola are the one shown and the one at infinity (the source of light rays).
Y= 210 you have to distribute 2/3 to y then to 57 and your equation would be 2/3y + 38= 178 then you take 38 and subtract 178 - 38 and you get 140 then you divide 140/ (2/3) and you will get 210 as your answer.(:
Answer:
This property states that if a = b, then b = a.
Step-by-step explanation:
That is, we can interchange the sides of an equation and the equation could still be true
B=6 i believe! if you use the pythagorean theorem (a^2+b^2=c^2) then you should be able to turn 8^2 and 10^2 into 64 and 100, respectively. 100-64=36 and the square root of 36 is 6. you can plug it in by calculating 8^2 + 6^2, which equals 100! hope this wasn't too confusing XD
Answer:
Probably y=2x+60
Step-by-step explanation:
It seemed to fit best, dont count on my answer tho, not 100% sure :(
When I put the line through the points, the y intercept was around 50/60 and the slope is positive so it eliminated a few answers. then I chose y=2x+60 since that slope seemed more correct than a slop of 8.
