Which of these systems of equations would be best solved using the subtraction​ method? I. 2x−7y+3y = 4
−6x−4y = −52
II. 2y = −5x+6x−5
y = 2x−6
III. −7x+3x+2y = 4
4x−6y = −52

diagram a has a slope of 4

diagram b has a slope of 1/4

diagram c has a slope of -1/4

Step-by-step explanation:

have a great day :D

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

7/2

(decimal: 3.5)
