Number of points Jill scored in the first 4 games = 4 * 4 = 16
number of points Jill scored in the first 4 games = 6 * 9 = 54
total points Jill scored in 10 games 16 + 54 = 70
the average number of points after 10 games = 70 / 10 = 7 points
-9x+2y = -36
when x=0 ; 2y = -36
so y = -18
then y-intercept(x=0) is -18
<span>L = (0.8) T^2
T^2 = L / 0.8
T = sqrt{ L / 0.8 }
T = sqrt{ 30 / 0.8 }
T = sqrt{ 37.5 }
T = 6.1 seconds
The correct answer is D) 6.1 seconds</span>
