Answer:
The factors of 8 are 1,2,4, and 8.
Step-by-step explanation:
An x intercept occurs whenever y=0.
y=(x-4)(x+2)
So for y=0, x=-2 or 4, so the x-intercepts are:
(-2, 0) and (4, 0)
Only (-2, 0) is within your answer choices.
So first (3 1/2) equals to 3+1/2 which is 7/2, same for(2 1/3), 2+1/3=7/3. It's asking for speed in laps per minute, so like how many labs did she swim per minute, which is labs over time——(7/2)/(7/3)=(7/2)*(3/7)=3/2. So she swam 3/2 labs per minute.
