Answer:
y = -x-3
x-y = -3
x - 2y = 10
Step-by-step explanation:
x − 3y = 6
Slope intercept form is y = mx +b
We need to solve for y
Subtract x from each side
x-x-3y = -x+6
-3y = -x +6
Divide each side by -3
-3y/-3 = -x/-3 +6/-3
y = 1/3 x -2
Standard form is Ax +By = C
y = -x-3
Add x to each side
x-y = -x+x-3
x-y = -3
y = 1/2x -5
We do not like fractions in standard form, so multiply by 2
2y = 2*1/2x -2*5
2y =x-10
Subtract x from each side
-x +2y = x-x-10
-x+2y = -10
We like to have the coefficient on x be positive
Multiply by -1
x - 2y = 10
The perimeter of the square is: 76.4 meters
Step-by-step explanation:
We have to find the side of square to find the perimeter
So
Area = A =
Let s be the side of the square
then
Putting the value of area
Taking square root on both sides
The side of square is 19.1 meters
Now
Let P be the perimeter
Then
The perimeter of the square is: 76.4 meters
