The value of y is (-2)

Step-by-step explanation:

To solve the linear equation, Number of unknown variables and number of equations must be same.

In given equation,

-6x+4y=-62 Equation 1

-3x-5y=-17 Equation 2

The number of Variable are 2,

So, To solve for value of y, we need to make use of two given equation and it can't be found from one single equation

Let multiply Equation 2 with 2 units

we get, -6x-10y=-34

Now, Subtracting both the equations

(-6x+4y)-(-6x-10y)=(-62)-(-34)

4y+10y=(-28)

14y=(-28)

y=(-2)

Therefore, the value of y is (-2)

A line passes through (2, 8) and (4, 12). Which equation best represents the line? y = 1 over 2 x 6 y = 2x 7 y = 2x 4 y = 1 over

nalin [4]

Equation of the line is a way to represent the a line in a equation or algebraic from which is the set of the line thorough witch the line passes.

Given information-

The point through which the line passes are (2, 8) and (4, 12).

To find the equation of the line, the standard form of the equation of the line must be obtained.

<h3>Equation of the line</h3>

Equation of the line is a way to represent the a line in a equation or algebraic from which is the set of the line thorough witch the line passes.

The standard form of the equation of the line can be given as,

$(y-y_1)=\dfrac{y_2-y_1}{x_2-x_1} (x-x_1)$

Where $(x_1,y_1)$ and $(x_2,y_2)$ are the points through which the line passes.

Thus the equation of the line which passes through the points (2, 8) and (4, 12) can be given as,

$(y-8) &=\dfrac{12-8}{4-2} (x-2)\\(y-8) &=\dfrac{4}{2} (x-2)\\2y-16 &=4x-8\\2y &=4x-8+16\\$

Divide by 2 both the side,

$y=2x-4$

Thus the equation of the line which passes through the points (2, 8) and (4, 12) is,

$y=2x-4$

Hence the option 3 is the correct option.

Find the volume of the solid- 2cm, 4.5cm, 3.5cm

kondaur [170]

For the volume of this solid, you’re first going to find the area of the front triangle. so base x height divided by 2. for this it would just be 4.5. then multiply that by the side length. so 4.5 x 3.5, which would be 15.75. so your answer would be 15.75 cubic centimeters
