Answer:
11/4
Step-by-step explanation:
To find the slope of a line given two points, we use the formula
m = (y2-y1)/(x2-x1)
= (-10-12)/(-7-1)
=-22/-8

Answer:
it will cost $ 354 and expression used is y= 3(16) + 34(9)
Step-by-step explanation:
Suppose the total cost is given by y $
y= 3(16) + 34(9)
y= 48+ 306
y= $354
Length= 2x-1. 2(7)-1=13
Width=X. =7
2x-1+2x-1+X+X=40
6x-2=40
Add 2
6x=42
Divide by 6
X=7
