Answer:
32
Step-by-step explanation:
The equation
and the graph below describe the velocity V in feet per second of a ball <em>t</em> seconds after it is shot into the air.
To find the balls velocity after seven seconds, substitute t = 7 into the function expression:

Hello,
I suppose equations are:
x+y=3 (1)
x+2y=9 (2)
(2)-(1)==>y=6
(1)==>x=3-6
x=-3, y=6
Sol={(-3,6)}
15r^2 - 14r -12 is the correct answer
Answer:
A. 150
Step-by-step explanation:
The image shows that the measure of DE is 30 degrees, so AD must also be 30 degress. Then you just simply subtract 30 degrees from 180 degrees and you'll end up with 150 degrees. Your welcome! :)
