Answer:
6x+2
Step-by-step explanation:
your combine like terms...
so 13x is teh same as -7x
13x-7x= 6x
3 and -1 are the same as well
3-1=2
so teh answer would be
6x+2
Answer:

Step-by-step explanation:
Because this quadratic equation would have the curve-down form of:

where a and b are positive coefficient.
If we let the peak (250 ft) of the curve be at x = 0. Then


Also at the begins and ends, thats where y = 0, the 2 points are separated by 100 ft. So let the begin at -50 ft and the end at 50ft. We have



Therefore, the model quadratic equation of our path would be

Y=-sqrt(x)+1
x must be greater than or equal to zero (positive): x>=0
Options Graphs 1 and 2
when x=0→y=-sqrt(0)+1=-0+1→y=1, then the graph must pass through the point (0,1)
Answer: Graph 2
