8x+2y=2
y=-5x+3

,7) b.(2,7)

c. no solution d.(0,-8)

(2,-7)

Step-by-step explanation:

Solve for x.

Plug in the value for y into the equation.

y=-5x+3

8x+2y=2

8x + 2(-5x+3)=2

8x-10x+6=2

         -6   -6

8x-10x = 2-6

8x-10x = -4

-2x = -4

÷ -2  ÷ -2

x = 2

Solve for y.

Plug in the value for x into the equation.

8x+2y=2

8(2) + 2y=2

16 + 2y = 2

- 16        - 16

2y = 2 - 16

2y = -14

÷ 2    ÷2

y = -7

Solve.

Determine if x and y values work.

8(2)+2(-7)=2

16-14=2

2=2

x and y values work so the answer is: (2,-7)

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

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
