Answer:the width of plywood = 6.25 feet wide or 6 1/4 feet wide
Step-by-step explanation:
Step 1
Area of a rectangular plywood = length x width
Area of Ist Plywood= 7 x w
Area of 2nd Plywood= 61/2 x w=6.5 xw
But Total Arae of trhe two Plywoods are = 84 3/8 square feet.
Therefore Our equation to solve the problem becomes
Area of Ist Plywood + Area of 2nd Plywood =84 3/8 square feet.
7w + 6.5w = 84 3/8
13.5w= 84 3/8
w = 84 3/8/13.5
675/8 / 13.5
w=6.25
Therefore the width of plywood = 6.25 feet wide or 6 1/4 feet.
The second option is correct, I,e what you've chosen
The equation of a horizontal line is
y
=
c
for some constant
c
Since we are told that the line passes through
(
x
,
y
)
=
(
−
4
,
6
)
Then for at least one point on the line
y
=
6
But for a horizontal line this value is a constant for all points on the line.
So the equation for all points on the line is
y
=
6
