Try plugging them in, might seem tedious, but it's the best way to practice. if you plug in a pair and the left side of the equation is less than or equal to 6, it's the right answer.

we have

2y-x\leq -6

we know that

if a ordered pair is a solution of the inequality

then

the ordered pair must satisfy the inequality

we will proceed to verify each case to determine the solution of the problem

<u>case A)</u> (0,-3)

Substitute the value of x and y in the inequality, if the inequality is true, then the ordered pair is a solution of the inequality

so

2*(-3)-0\leq -6

-6\leq -6 -------> Is True

therefore

the ordered pair (0,-3) is a solution of the inequality

<u>case B)</u> (2,-2)

Substitute the value of x and y in the inequality, if the inequality is true, then the ordered pair is a solution of the inequality

so

2*(-2)-2\leq -6

-6\leq -6 -------> Is True

therefore

the ordered pair  (2,-2) is a solution of the inequality

<u>case C)</u> (1,-4)

Substitute the value of x and y in the inequality, if the inequality is true, then the ordered pair is a solution of the inequality

so

2*(-4)-1\leq -6

-9\leq -6 -------> Is True

therefore

the ordered pair  (1,-4) is a solution of the inequality

<u>case D)</u> (6,1)

Substitute the value of x and y in the inequality, if the inequality is true, then the ordered pair is a solution of the inequality

so

2*(1)-6\leq -6

-4\leq -6 -------> Is False

therefore

the ordered pair  (6,1) is not a solution of the inequality

case E) (-3,0)

Substitute the value of x and y in the inequality, if the inequality is true, then the ordered pair is a solution of the inequality

so

2*(0)-(-3)\leq -6

3\leq -6 -------> Is False

therefore

the ordered pair  (-3,0) is not a solution of the inequality

therefore

<u>the answer is</u>

(0,-3)

(2,-2)

(1,-4)

e-lub [12.9K]
You will choose 1 cheese 3 different ways because there are three types of cheeses.

You will choose your topings 6 different ways. 4!/(2!2!) = 4*3/2 = 6

Therefore you will be able to get 6 * 3 different pizzas = 18 pizza combinations.

To confirm the toppings, suppose they are (M)ushrooms (P)epperoni (O)nions and (B)acon

What is the distance between the points (-6,5) and (8,-2) on a coordinate plane?
Naddik [55]

Distance Formula: D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2

Apply the points: D=\sqrt{(8-(-6))^2+((-2)-5)^2

Solve: D=\sqrt{(8-(-6))^2+((-2)-5)^2}\\D=\sqrt{14^2+(-7)^2}\\D=\sqrt{169+49}\\D=\sqrt{218}

Since the square root of 218 cannot be simplified, the answer is

D=\sqrt{218}

Soccer balls go on sale for $7.50 each. The store also sells footballs and the manager wants to earn a daily profit of $400 from
Tasya [4]
At $7.50 per soccer ball, they earn a daily profit of $232.50.
The store needs to earn a daily profit of $400 – $232.50 = $167.50 from footballs.
Solve 167.50 = –4x2 + 80x – 150 to find the price for footballs: x = $5.46 and $14.54.
