The axis of symmetry is x=3
The answer is for this question is A
The slope is the rate in which he is moving and the y-intercept is where he started (at 0 seconds and 0 meters).
A^2+b^2=c^2
10^2+24^2=c^2
100+576=c^2
676=c^2
c=26
The length of the hypotenuse is 26.
I hope this helps!! :)
The expression is n/2 + 3 = 7
