For each relation, decide whether or not it is a function. Relation 1 DomainRangecloud 7 rock 3 sun −9 lake −1 Function Not a function Relation 2 DomainRange7 3 −1 1 −9 −8 3 4 Function Not a function Relation 3 , eh,, rt,, rr,, ee Function Not a function Relation 4 , 4n,, 5n,, 5h,, −2z Function Not a function

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.

answer: the common difference is -0.10

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
