Given that the equation -2x+3y=9

We need to determine the coordinate that is not a solution to the equation.

<u>Option A</u>: (0,3)

Substituting the coordinate (0,3) in the equation -2x+3y=9, we get;

-2(0)+3(3)=9

           0+9=9

                 9=9

Since, both sides of the equation are equal, then the coordinate (0,3) is a solution to the equation.

Hence, Option A is not the correct answer.

<u>Option B</u>: (1,-3)

Substituting the coordinate (1,-3) in the equation  -2x+3y=9, we get;

-2(1)+3(-3)=9

           -2-9=9

               -11\neq 9

Since, both sides of the equation are not equal, then the coordinate (1,-3) is not a solution to the equation.

Hence, Option B is the correct answer.

<u>Option C</u>: (-3,1)

Substituting the coordinate (-3,1) in the equation  -2x+3y=9, we get;

-2(-3)+3(1)=9

              6+3=9

                    9=9

Since, both sides of the equation are equal, then the coordinate (-3,1) is a solution to the equation.

Hence, Option C is the correct answer.

Therefore, the coordinate (1,-3) is not a solution to the equation -2x+3y=9

1. using 2 dots that are on the blue line (0,72) and (6,69)
find the slope:

slope = change in Y over change in x = 69 - 72 / 6-0 = -3 / 6 = -1/2
 equation would be y = -1/2x + 72

2. y = -1/2x+72 = -1/2(30) +72 = -15 +72 = 57 beats per minute

3. replaced x in the equation with 30 to find the beats per minute for exercising 30 minutes

What is the vertical asymptotes of the function f(x)=x-2/x*2-3x-4
frozen [14]

Answer:

<h2>x = -1 and x = 4</h2>

Step-by-step explanation:

f(x)=\dfrac{x-2}{x^2-3x-4}\\\\\text{DOMAIN}:\\\\x^2-3x-4\neq0\\\\x^2-4x+x-4\neq0\\\\x(x-4)+1(x-4)\neq0\\\\(x-4)(x+1)\neq0\iff x-4\neq0\ \wedge\ x+1\neq0\\\\x\neq4\ \wedge\ x\neq-1\\\\\text{Therefore the vertical asymptotes are:}\\\\x=-1\ and\ x=4.

Scientist A dissolved 1.0 kilogram of salt in 3.0 liters of water. Scientist B dissolved 2.0 pounds of salt into 7.0 pints of wa
solong [7]

The scientist that made a more concentrated salt solution is scientist A.

<h3>How to compute the value?</h3>

Since Scientist A dissolved 1.0 kilogram of salt in 3.0 liters of water. The concentration will be:

= 1/3 = 0.33

Scientist B dissolved 2.0 pounds of salt into 7.0 pints of water. The concentration will be:

= 2/7

= 0.285

Therefore, the scientist that made a more concentrated salt solution is scientist A.
