9950x=8650x+250000
Subtract 8650x from both sides
1300x= 250000
I believe the equation would be 765 -8t = 421. Then you would solve for t and get 43 seconds. I hope this helps!! :)
Answer:
We need to subtract both equations. 2x3+30x-130-2x3+3x+520
that gives
30x-130+3x + 520
33x+390
D is answer
What you need to do is add the two equations and combine like terms to get h(x). Refer to the photo for a better explanation.
