Answer:
<em>y = 1/2x + 2 1/2</em>
Step-by-step explanation:
y - 4 = 1/2 (x - 3)
y - 4 = 1/2x - 3/2
y = 1/2x - 3/2 + 4
y = 1/2x + 2 1/2
Answer:
$40
Step-by-step explanation:
This isn't the proper way to do this but
5×20=100 so you multiply the $2 by 20
The answer is zero hope that helps
AD is the width side of the perimeter is 78
So they said AD is more than twice AB
78 multiply 2= 156
You have 2 width 78+78
You have 2 length 156+156
Add four sides together
Hope this help you!
