Answer:

no solutions.

Step-by-step explanation:

8x + 14 -4x = 9+4x -5

8x-4x -4x = 9-5-14

0x = -10

anything multiplied by 0 is 0, so it's impossible to get -10 by multiplying by 0

Which expressions are equivalent to g+h+ (j+k)? Check all that apply.

Vsevolod [243]

According to the associative property of equality: (a + b) + c = a + (b + c) we can see that the parenthesis do not mean anything when we are only doing addition.

So answers 1. and 3. are correct.

Thanks Associative Property!

Answer:

Infinite solutions

Step-by-step explanation:

Given is a system of equations.

-3x+y=10

-6x+2y=20

Equation I when multiplied by 2, gives as

-6x+2y =20 which is the same as equation 2 given.

This gives the two lines are not intersecting nor parallel. But the two lines are coincident with each other.

Hence each point on the line is solution.

Infinite solutions.

Let us try to solve and verify this

BY substitutition we have y = 3x+10, substitute in II

-6x+2(3x+10) =20

Or -6x+6x+20=20

20=20 Thus for any x, this becomes true.

Hence infinite solutions.

Hi !

Judy built a rectangular patio that is 9 meters wide and has a perimeter of 40 meters what is the length of Judy’s patio ?

$l=9\;m\\L=x$

$So\;Perimeter=2(9+x)=18+2x=40\;m\\\\18+2x=40\\2x=40-18\\2x=22\\\\x=\dfrac{22}{2}\\\\\boxed{x=L=11}$

The lenght of Judy's Patio is 11 meters.
