Your answer will be D. Hope I helped.
a) 32/8= 4
32/20= 1.6
84/30= 2.8
100/40= 2.5
4+1.6+2.8+2.5= 10.9
10.9/4=2.725 so on average the bassett travels 2.725 yards per second
b) the bassett stops moving for 12 seconds, I know this because between seconds 8 and 20, there is no rise in yards
c) 20 to 30 seconds because it has the steepest increase in yards, with the least time passed.
The slope is -1/4. Hope this helps! Please mark brainliest! Thank you v much! :)
Erm
x+y=6
xy=12
x+y=6
y=6-x
sub back
xy=12
x(6-x)=12
6x-x^2=12
x^2-6x=-12
x^2-6x+12=0
quadratic formula
for
ax²+bx+c=0

for
x²-6x+12=0
a=1
b=-6
c=12
and remember that √-1=i






x=3+/-i√3
the numbers are 3+i√3 and 3-i√3
no real numbers tho
