The coefficient is negative because she is traveling downward. -20ft/s represents feet decreasing per second.

She was 350 feet above ground since that is her height at 0 seconds.

Add the two expressions.<br><br> −4x+3 and 2x−6<br><br> Enter your answer in the box.
BlackZzzverrR [31]
First, you set your problem up like this: 

-4x+3=2x-6

add 6 to both sides so it looks like this:

-4x+9=2x

add 4x to both sides so it looks like this:

9=6x

divide 6 from both sides so this is your answer:

1.5=x

Bingel [31]

Answer:

280=8x + 130

Step-by-step explanation:

Im pretty sure this is correct it has been a while since I did this but y is the total amount so y is 280. M is the slope so it would be how often the amount changes so m is 8. x is unknown and what needs to be solved for. b is the y intercept which is just the initial amount of 130.
