-x - 9 \geq 5

You want to get x by itself.

First subtract 9 from both sides of the equation.

-x - 9 \geq 5
    +9                 +9

-x \geq 14

Then divide -1 on both sides.

-x/-1 \geq 14/-1

I'm pretty sure when you divide a negative number when solving inequalities, you switch the sign.

x \leq 5

Solve the given system of equations. 2y= -x+9 , 3x-6= -15
poizon [28]

Answer:

<h2>x = -3, y = 6 → (-3, 6)</h2>

Step-by-step explanation:

\left\{\begin{array}{ccc}2y=-x+9\\3x-6=-15&\text{add 6 to both sides}\end{array}\right\\\left\{\begin{array}{ccc}2y=-x+9\\3x=-9&\text{divide both sides by 3}\end{array}\right\\\left\{\begin{array}{ccc}2y=-x+9\\x=-3\end{array}\right\qquad\text{put the value of x to the first equation}\\\left\{\begin{array}{ccc}2y=-(-3)+9\\x=-3\end{array}\right\\\left\{\begin{array}{ccc}2y=3+9\\x=-3\end{array}\right\\\left\{\begin{array}{ccc}2y=12&\text{divide both sides by 2}\\x=-3\end{array}\right\\\left\{\begin{array}{ccc}y=6\\x=-3\end{array}\right

Ben is decorating his home with vases of flowers. He bought glass vases that cost $22 each and ceramic vases that cost $14 each.
Ksivusya [100]

Number of glass vases bought = x

Number of ceramic vases = y

Ben bought no more than 10 vases in all.

So total number of vases can be represented as:

x+y\leq10

Cost of one glass vase = $22

Cost of x glass vases = 22x

Cost of one ceramic vase = $14

Cost of y ceramic vases = 14y

Total cost of vases is more than $172

So the equation for cost is:

22x+14y\geq172

Answer:

So the system of inequalities that can be used are:

x+y\leq10

22x+14y\geq172
