Graph the following system of equations and find the x-coordinate of the solution.

Veseljchak [2.6K]

The x - coordinate of the solution is $x=-2$

Explanation:

The two equations are $3 x+3 y=3$ and $y=-\frac{1}{2} x+2$

Let us determine the value of the x - coordinate using the substitution method.

Let us substitute $y=-\frac{1}{2} x+2$ in the equation $3 x+3 y=3$ , we get,

$3x+3(-\frac{1}{2} x+2)=3$

Multiplying the term 3 within the bracket, we get,

$3x-\frac{3}{2} x+6=3$

Subtracting both sides of the equation by 6, we get,

$3x-\frac{3}{2} x=-3$

Taking LCM on the LHS of the equation, we get,

$\frac{6x-3x}{2} =-3$

Subtracting the numerator, we have,

$\frac{3x}{2}=-3$

Multiplying both sides of the equation by 2, we have,

$3x=-6$

Dividing both sides of the equation by 3, we get,

$x=-2$

Thus, the x - coordinate of the solution is $x=-2$

How would you solve for x and y and what are x and y? Not sure what to do.

Ivahew [28]

Answer:

x = 26 2/3

y = 50

Step-by-step explanation:

you could set '2y-3x' equal to '-3x+y+50' because they are vertical angles

2y - 3x = -3x + y + 50

add 3x to each side to get:

2y = y + 50

y = 50

also, we know that (1/2y + 25) + (2y - 3x) = 180 because they form a straight line

3/2y + 25 - 3x = 180

subtract 25 from each side to get:

3/2y - 3x = 155

substitute 50 for 'y' to get:

3/2(50) - 3x = 155

75 - 3x = 155

-3x = 80

x = 26 2/3

Answer:

<h2>CYLINDER</h2>

Surface Area = 471.2 cm^2

<h2>TRIANGULAR PRISM</h2>

Surface Area = 60.75 m^2

Step-by-step explanation:

<h2>CYLINDER</h2>

The surface area formula for a cylinder is π x diameter x (diameter / 2 + height), where (diameter / 2) is the radius of the base (d = 2 x r), so another way to write it is π x radius x 2 x (radius + height). ( π =3.14 )

FORMULA:

π x 5 x 2 x 15

WORK:

π x 5 = 15.7

15.7 x 2 = 31.4

31.4 x 15 = 471

<h2>TRIANGULAR PRISM</h2>

The surface area formula for a triangular prism is 2 * (height x base / 2) + length x width1 + length x width2 + length x base.

FORMULA:

2 x (2.5 x 1.5/2) + (6 x 4) + (6 x 4) + (6 x 1.5)

WORK:

(2.5 x 1.5) = 3.75/2 = 1.875

1.875 x 2 = 3.75

(6 x 4) = 24

(6 x 4) = 24

(6 x 1.5) = 9

3.75 + 24 + 24 + 9 = 60.75
