x=3
f (3)=4.3^2-8.3+3
f (3)=36-24+3=15
f (3)=4.3^2-8.3-3=36-24-3=5
The graph is to the left of -3, so it's < or ≤.
The circle is filled in so -3 also satisfies the inequality, so it's ≤.
The answer is B. x≤-3.
The new player's personal time is 4.5 seconds.
<h3>What is the new player's personal time?</h3>
The first step is to determine the total time the 5 persons complete the dash.
Total time = 5 x 5.7 = 28.5 seconds
The second step is to determine the total time for the 6 people to complete the dash.
Total time = 6 x 5.5 = 33 seconds
The third step is to find the difference of the time in the previous two steps: 33 - 28.5 = 4.5 seconds
