Let
y----------> the length of the rectangle
x---------> the width of the rectangle
P--------> perimeter of a rectangle
we know that
P=38 ft
[P]=2*[x+y]------> 38=2*[x+y]------> equation 1
y=5+x-------> equation 2
<span>substitute 2 in 1
</span>P=2*[x+(5+x)]---------> P=4x+10---------> the given equation
4x=38-10--------> 4x=28----> x=7 ft
y=5+7-----> y=5+7------> y=12 ft
the answer is
the width is 7 ft
X is less than two
the graph line goes to the left, indicating the value of x is negative/less than two. It’s not equal to since the circle isn’t filled
Answer:
D (7, 0.5)
Step-by-step explanation:
The equations must be interpreted to be ...
A graph shows the solution to be (7, 0.5), matching selection D.
___
You can add the two equations together to get ...
(y) +(y) = (-1/2x +4) + (1/2x -3)
2y = 1 . . . . . simplify
y = 1/2 . . . . .divide by 2
It can be convenient to use the second equation to find x.
1/2 = 1/2x - 3
1 = x - 6 . . . . . . multiply by 2
7 = x . . . . . . . . . add 6
The solution is (x, y) = (7, 0.5). . . . . matches selection D.

i think this is the right answer as you did not put the whole question
so i assume it keeps on going up in 2s.
hope this helps
Answer:
Opt B.
Step-by-step explanation:
Remember that the equation of a line tells us that y=mx+b, where m is the slope (Which we have and is -8), just need to find b, for that, lets eval the given point (1,-5) in the above equation.
-5=-8*1+b
Where we obtain that b=3
Our line is written as y=-8x+3
And in standard form that would be (grouping variables in the same side of equality sign)
y+8x=3
