Answer:
The formula is 1/2 * b*h or b*h divided by 2
Step-by-step explanation:
36*4=144 -> 144/2=72.
Answer:
1/5
Step-by-step explanation:
-5 - (-7) = 2
5 - (-5) = 10
2/10 ÷2
slope = 1/5
Answer:
y<5
Step-by-step explanation:
y+8 < 13
y < 13-8
y < 5
The midpoint of the line having the endpoints

and

is

basically average them
so given that the line has the endpoints of (-3,7) and (9,-2)
x₁=-3
y₁=7
x₂=9
y₂=-2
so the midpoint can be found by doing



the midpoint is
Y=mx
m=amount of time per day studied
y=time
x=number of days
we have
60=m(4)
divide by 4
15=m
y=15x
