2-(-4)
--------= 6
-1-7 ---= 3/4
8
y=3/4x
-4=3/4 (7)+b
-4=21/4+b
-4-21/4= -37/4
21/4-21/4=0
y=3/4x-37/4
Answer:
1) is equivalent multiply by 6
2) is equivalent multiply by 2 to 5/2
What we know:
Lot= 21 x 30ft
Perimeter=2l+2w
Want to put 4 corner post and one post every 3 ft
What we need to find:
How many post we need.
Perimeter=2 (21)+2 (30)=42+60=102ft
102/3=34
34 posts are needed.
=3,915
product is use for multiplying
