Answer:

-11/12

Step-by-step explanation:

→ Find change in y

-7 --18 = 11

→ Find change in x

-1 - 11 = -12

→ Divide each other

-11/12

Answer:

-4

Step-by-step explanation:

There are many methods to solve this system of equations.

I will use the elimination method.

First step:

Multiply the first equation by -2

2(2x-3y) = -14(-2)

-4x + 6y = 28

Multiply the second equation by 3 so you can eliminate the y term

3(3x-2y) = -6(3)

9x-6y = -18

Second step: Add the equations vertically(Basically adding like terms)

-4x+6y = 28

     +

9x - 6y = -18

5x = 10

Third step: Solve for x

\frac{5x}{5}  = \frac{10}{5}

x = 2

Substitute the x-value into any of the original equation to get the y value

3(x) - 2y = -6

3(2) - 2y = -6

6 - 2y = -6 (Since we are solving for y, it will be isolated and we will move 6 to the other side)

-2y = -6 - 6(Moving 6 to the other side makes it negative)

Solve for y by dividing by -2

\frac{-2y}{-2} = \frac{-12}{-2}

y = 6

So (x, y) = (2, 6)

Since the question is asking to subtract x and y

2-6 = -4

Answer:

The height of right circular cone is h = 15.416 cm

Step-by-step explanation:

The formula used to calculate lateral surface area of right circular cone is: s=\pi r\sqrt{r^2+h^2}

where r is radius and h is height.

We are given:

Lateral surface area s = 236.64 cm²

Radius r = 4.75 cm

We need to find height of right circular cone.

Putting values in the formula and finding height:

s=\pi r\sqrt{r^2+h^2}\\236.64=3.14(4.75)\sqrt{(3.75)^2+h^2} \\236.64=14.915\sqrt{(3.75)^2+h^2} \\\frac{236.64}{14.915}=\sqrt{14.0625+h^2}  \\15.866=\sqrt{14.0625+h^2} \\Switching\:sides\:\\\sqrt{14.0625+h^2} =15.866\\Taking\:square\:on\:both\:sides\\(\sqrt{14.0625+h^2})^2 =(15.866)^2\\14.0625+h^2=251.729\\h^2=251.729-14.0625\\h^2=237.6665\\Taking\:square\:root\:on\:both\:sides\\\sqrt{h^2}=\sqrt{237.6665} \\h=15.416

So, the height of right circular cone is h = 15.416 cm
