Answer:
(4s-3)ft
Step-by-step explanation:
The 3 sides of the room will be "s" ft long. The 4th side, the one with the doorway will be "s-3" ft long, the -3 because of the doorway. Then you simply add all the sides of the doorway to get the length for the metal strip.
You would divide the total area by the length.
8 3/4 divided by 3 1/2
35/4 / 7/2
35/4 * 2/7 = 70/28 =2 1/2 ft
Answer : <em>Equation of line is</em> y=Equation of line is y=
x+![\frac{-5}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B-5%7D%7B3%7D)
Step-by-step explanation:
Theory :
Equation of line is given as y = mx + c.
Where, m is slope and c is y intercepted.
Slope of given line : y =
x+1 is m= ![\frac{2}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D)
We know that line : y =
x+1 is parallel to equation of target line.
therefore, slope of target line will be
.
we write equation of target line as y=
x+c
Now, It is given that target line passes through point ( -5,-2)
hence, point ( -5,-2) satisfy the target line's equation.
we get,
y=
x+c
-2=
-5+ c
-5=
+c
c= ![\frac{-5}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B-5%7D%7B3%7D)
thus, Equation of line is y=Equation of line is y=
x+![\frac{-5}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B-5%7D%7B3%7D)
