Answer:
see explain
Step-by-step explanation:
3 - 5
(X1, Y1) (X2, Y2)
which turns to at least for number 3
(11 - 8) / (-2 - 6) = -3 / 8 = -0.375
think you can figure out the rest.
then for #1 and 2
do the same thing, except choose any two points on the graphs.
for example you could choose (-1, 0) and (0, -2) for #1
in the equation this would be (-2 - 0) / (0 - (-1) = (-2)/1 = -2
It would be the bottom triangle is 60 the right triangle is 36 the left rectangle is 24 and the left triangle is 12 so u add them together and get 132 units squared
The percentage of boys in the class is 55%. This is because there are 20 people in the class, and 11/20= .55, or 55%
1200 milligrams because 400 times 3 would equal a full 24 hours
