Answer:

\displaystyle -\frac{1}{3} ≥ y

Step-by-step explanation:

\displaystyle \frac{-3(5y - 4)}{-3} ≥ \frac{17}{-3}

5y - 4 ≤ –5⅔

+ 4 + 4

__________

\displaystyle \frac{5y}{5} ≤ \frac{-1\frac{2}{3}}{5} \\ \\ y ≤ -\frac{1}{3}

Whenever you divide\multiply by a negative, you reverse the inequality symbol.

* Use the zero-interval test [test point (0, 0)] to determine whether we shade the opposite portion [the portion that does not contain the origin] or the portion that DOES contain the origin. This is where we verify the inequality as false or true:

\displaystyle 0 ≰ -\frac{1}{3}

This is a false statement, so we shade the opposite portion of the line.

I am joyous to assist you anytime.

(  ) are used when the point is not consider in the interval.

[  ]  are used when the point is consider or is part of the interval.

Also, an empty point indicates that the number is not consider in the interval.

and, a filled point indicates that the number is consider in the interval.

For your question, the interval will be:

What is the solution to the following system of equations? x − 4y = 6 2x + 2y = 12 (0, 10) (10, 0) (6, 0) (0, 6)
frozen [14]

Answer:

(6,0)

Step-by-step explanation:

The given system has equations:

x-4y=6

2x+2y=12

Multiply the top equation by 2 to get:

2x-8y=12

2x+2y=12

Subtract the top equation form the bottom equation to get:

2x-2x+2y--8y=12-12

\implies 10y=0

\implies y=0

Put y=0 into x-4y=6

x-4*0=6

\implies x=6

Therefore the solution is (6,0)
