Which of the following ordered pairs is a solution of the given system of linear equations?
x+1=y
2x-y=0
a. (1, –2)
b. (1, 2)
c. (2, 1)
d. (–2, 1)

Option B is correct

(1, 2)

Step-by-step explanation:

Given the system of equation:

              ......[1]

           ....[2]

We can rewrite [2] as:

2x = y                 ....[3]

Substitute this in [1] we have;

⇒

or

x = 1

Substitute in [3] we have;

∴Solution = (1, 2)

Therefore, the following ordered pairs is a solution of the given system of linear equations is, (1, 2)

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
